Description
本新型是有關於一種葉片裝置，特別是指一種能受風力驅動轉動，可應用於風力發電設備的風力葉片裝置。The present invention relates to a blade device, and more particularly to a wind blade device that can be driven by wind power and can be applied to a wind power generation device.
本案申請人先前已提出一種風力發電裝置之創新結構，其專利證書號為M485960，該專利所提供的風力發電裝置主要包含：一轉軸，及數個連接該轉軸且彼此角度間隔的葉片模組。每一葉片模組包括一連接該轉軸的格柵式葉片，以及數個可前後擺動地垂掛於該格柵式葉片上的擺動葉片。該風力發電裝置主要是藉由任一葉片模組中迎風面側旋轉過軸心至背風面側時，透過擺動葉片的迎風面閉合及背風面的開啟而產生軸心兩邊之扭力差異而運轉，藉此能提高裝置整體之旋轉扭力與風力使用效率。但申請人發現，因靠近裝置外側的風力葉片離軸心的距離較遠，當旋轉使用時，裝置之外圍的轉動速率較快、離心力也較大，當任一葉片模組旋轉至迎風面時，該葉片模組之位於外圍的該等擺動葉片下方所設置的配重件，會因外側的離心力較大而使配重件不易及時垂下以使擺動葉片完全閉 合，從而造成當葉片模組再轉動至迎風面側時，擺動葉片的迎風擋風面積較小而導致旋轉扭力效率因此下降。因此，位於該風力發電裝置外側的擺動葉片，較佳地應以其他種葉片結構來取代。The applicant of the present invention has previously proposed an innovative structure of a wind power generation device, and the patent certificate number is M485960. The wind power generation device provided by the patent mainly comprises: a rotating shaft, and a plurality of blade modules connected to the rotating shaft and angularly spaced from each other. Each of the blade modules includes a grille blade connected to the rotating shaft, and a plurality of swinging blades that are slidable back and forth on the grille blade. The wind power generator is mainly operated by rotating the windward side of the blade module to the leeward side of the blade module, and closing the windward surface of the swinging blade and opening the leeward surface to generate a difference in torque between the two sides of the shaft. Thereby, the overall rotational torque and the wind power use efficiency of the device can be improved. However, the Applicant has found that because the distance of the wind blade near the outside of the device is far from the axis, when rotating, the rotation speed of the periphery of the device is faster and the centrifugal force is larger, when any blade module rotates to the windward side. The weight member disposed under the swinging blades of the blade module may have a large centrifugal force on the outer side, so that the weight member is not easily suspended in time to completely close the swinging blade. Therefore, when the blade module is rotated to the windward side, the windward windshield area of the oscillating blade is small, resulting in a decrease in the rotational torque efficiency. Therefore, the oscillating blades located outside the wind power generator should preferably be replaced by other kinds of blade structures.
因此，本新型之目的，即在提供一種可提升風力運轉效率的風力葉片裝置。Accordingly, it is an object of the present invention to provide a wind blade apparatus that can improve the efficiency of wind power operation.

The weights 23 can be used to increase the weight of the oscillating blades 22 such that the oscillating blades 22 can be suspended and have sufficient weight to swing.
每一葉片模組2的該等葉杯24為陣列式且彼此間隔地排列。在該轉軸1之徑向方向上，該等葉杯24相對於該等擺動葉片22遠離該轉軸1。亦即，該等葉杯24鄰近該格柵21的外側214而設置，該等擺動葉片22相對於該等葉杯24鄰近該格柵21的內側213而設置。每一葉杯24穿設固定在其中一第一柵桿211與其中一第二柵桿212上。具體來說，在該格柵21的靠近該外側214處，任一第一柵桿211與任一第二柵桿212的相交處，即設有一個葉杯24。該等葉杯24固定於第一柵桿211及第二柵桿212的方式，例如可以利用緊配合穿套固定，並進一步地可藉由繩帶穿綁固定、黏膠黏固，或者也可以是其他固定方式。每一葉杯24包括一向內凹陷且界定出一個杯空間240的內表面241，以及一相反於該內表面241且朝向該運轉方向T的外表面242。每一葉杯24的外表面242具有一中央突部243，該中央突部243相當於該葉杯24最突出的部位。本實施例之部分葉杯24約呈半球殼形，部分葉杯24約呈四分之一球殼形，部分葉杯24約呈八分之一球殼形。The vane cups 24 of each blade module 2 are arrayed and spaced apart from one another. In the radial direction of the spindle 1, the vanes 24 are remote from the spindle 1 with respect to the pivoting vanes 22. That is, the vane cups 24 are disposed adjacent to the outer side 214 of the grille 21, and the swinging vanes 22 are disposed adjacent to the inner side 213 of the grille 21 with respect to the vane cups 24. Each of the leaf cups 24 is disposed to be fixed to one of the first grid bars 211 and one of the second grid bars 212. Specifically, a vane 24 is provided at the intersection of any of the first grid bars 211 and any of the second grid bars 212 near the outer side 214 of the grid 21. The manner in which the leaf cups 24 are fixed to the first grid bar 211 and the second grid bar 212 can be fixed by, for example, a tight fit, and can be further fixed by a strap, glued, or Is another fixed way. Each of the leaf cups 24 includes an inner surface 241 that is recessed inwardly and defines a cup space 240, and an outer surface 242 that is opposite the inner surface 241 and that faces the running direction T. The outer surface 242 of each leaf cup 24 has a central projection 243 that corresponds to the most prominent portion of the leaf cup 24. Some of the leaf cups 24 of this embodiment are approximately hemispherical shell-shaped, some of the leaf cups 24 are approximately one-quarter of a spherical shell shape, and some of the leaf cups 24 are approximately one-eighth of a spherical shell shape.
本新型之葉杯24可以為硬式材料製成的葉杯24，也可以為軟式材料製成的葉杯24。硬式材料例如金屬、玻璃纖維、硬質塑膠、天然硬質材料或其他硬質之高分子材料等硬質材質製成。軟式材料例如布類、帆布類、尼龍布類、橡膠、軟質塑膠或其他軟質高分子材料等軟性材質製成。在本實施例中，是以軟式葉杯24為例，當葉杯24受到風吹動與填充後，可呈現飽滿之未完整的球殼狀，當 葉杯24處於非迎風位置時，則呈現皺摺狀。但實際上，該等葉杯24之材質不須限制，只要能承受風力即可。The leaf cup 24 of the present invention may be a cup 24 made of a hard material or a cup 24 made of a soft material. Hard materials such as metal, fiberglass, hard plastic, natural hard materials or other hard polymer materials. Soft materials such as cloth, canvas, nylon cloth, rubber, soft plastic or other soft polymer materials. In this embodiment, the soft leaf cup 24 is taken as an example. When the leaf cup 24 is blown and filled by the wind, it can be full and full of spherical shell shape. When the leaf cup 24 is in the non-windward position, it is wrinkled. However, in fact, the material of the cup 24 is not limited, as long as it can withstand the wind.
該等加強片25分別設置於該等葉杯24的內表面241且對應該中央突部243的位置。該等加強片25的材質例如布類、帆布類、尼龍布類、橡膠、金屬、玻璃纖維等等，其功能用於加強葉杯24之中央突部243部位的結構強度。The reinforcing sheets 25 are respectively disposed on the inner surface 241 of the cup 24 and correspond to the position of the central protrusion 243. The material of the reinforcing sheets 25 is, for example, cloth, canvas, nylon cloth, rubber, metal, glass fiber or the like, and its function is to strengthen the structural strength of the central projection 243 of the cup 24.
每一葉片模組2的該等加強桿26沿該徑向方向間隔排列，並且皆沿該軸向方向A延伸，該等加強桿26的位置分別與其中幾個第一柵桿211間隔相對。每一加強桿26同時連接該等葉杯24的其中幾個的中央突部243。具體而言，本實施例的每一葉片模組2的加強桿26數量為兩個，每一加強桿26連接其中數個位於同一第一柵桿211上的葉杯24的中央突部243。由於本實施例的葉杯24為軟式材料製成，當葉杯24未處於迎風位置時，尤其是位於逆風位置並受到逆向風吹動時(此處指風由葉杯24的外表面242方向吹送而來)，葉杯24有可能會被吹動而反向凹陷，亦即，此時該外表面242變成向內凹陷，該內表面241則變成朝外突出。而為了避免此問題，因此較佳地，可以如本實施例藉由該等加強桿26連接葉杯24的中央突部243，以將該等中央突部243拉撐住，避免葉杯24受到逆向風吹動時反向凹陷。The reinforcing bars 26 of each blade module 2 are spaced apart in the radial direction and extend in the axial direction A. The positions of the reinforcing bars 26 are respectively spaced apart from the first grating bars 211. Each of the reinforcing bars 26 simultaneously connects the central protrusions 243 of several of the cups 24. Specifically, the number of the reinforcing bars 26 of each of the blade modules 2 of the present embodiment is two, and each of the reinforcing bars 26 connects the central protrusions 243 of the plurality of cups 24 on the same first grating bar 211. Since the leaf cup 24 of the present embodiment is made of a soft material, when the leaf cup 24 is not in the windward position, especially when it is in the upwind position and is subjected to the reverse wind blow (here, the wind is blown by the outer surface 242 of the leaf cup 24). As a result, the leaf cup 24 may be blown and recessed in the opposite direction, that is, at this time, the outer surface 242 becomes inwardly recessed, and the inner surface 241 becomes outwardly protruded. In order to avoid this problem, it is preferable to connect the central protrusions 243 of the leaf cups 24 by the reinforcing rods 26 as in the present embodiment to pull the central protrusions 243 to prevent the cup cups 24 from being received. Reverse sag when the reverse wind blows.
每一葉片模組2的擋風導流片27略呈弧形長板片狀，並連接在該格柵21之外側214，且沿該運轉方向T 反向延伸。The wind deflector 27 of each blade module 2 has a slightly curved long plate shape and is connected to the outer side 214 of the grating 21, and along the running direction T Reverse extension.
本新型使用時，每一擺動葉片22可在一關閉位置與一開啟位置間移動(圖1即顯示部分的擺動葉片22關閉，部分的擺動葉片22開啟)。在該關閉位置時，每一擺動葉片22的擺動端222貼靠該格柵21，且該擺動葉片22覆蓋與其對應的該葉片空間210。在該開啟位置時，每一擺動葉片22的擺動端222遠離該格柵21，而且此時該擺動葉片22不再覆蓋與其對應的該葉片空間210，從而使逆向風力流場可通過葉片空間210而吹送。In the present invention, each of the oscillating vanes 22 is movable between a closed position and an open position (Fig. 1 shows that the oscillating vanes 22 of the display portion are closed and a portion of the oscillating vanes 22 are opened). In the closed position, the oscillating end 222 of each oscillating blade 22 abuts against the grid 21, and the oscillating blade 22 covers the blade space 210 corresponding thereto. In the open position, the oscillating end 222 of each oscillating blade 22 is remote from the grid 21, and at this point the oscillating blade 22 no longer covers the blade space 210 corresponding thereto, such that the reverse wind flow field can pass through the blade space 210. And blowing.
具體來說，以一通過該轉軸1之軸線來作分界，該轉軸1下方靠右側的該葉片模組2處於接受迎風面風壓之順向風壓側，在此同時，該轉軸1中心上方的葉片模組2及下方靠左側的葉片模組2則位於背風面之逆向風壓側。下方右側的該葉片模組2受到一迎風風力F1吹動時，由於該葉片模組2的該等擺動葉片22位於格柵21之迎風側，會被吹動而貼靠在該格柵21上，且位於該關閉位置並覆蓋葉片空間210，該等擺動葉片22進而與該格柵21搭配，於該迎風側共同構成一完整的迎風表面，可提升扭力旋轉效率，使本新型可受到風力推動而連同該轉軸1一起朝該運轉方向T轉動。Specifically, the blade module 2 on the right side of the rotating shaft 1 is on the forward wind pressure side of the windward side of the windward direction, and the center of the rotating shaft 1 is above the center. The blade module 2 and the blade module 2 on the left side are located on the reverse wind pressure side of the leeward surface. When the blade module 2 on the lower right side is blown by a windward wind F1, since the oscillating blades 22 of the blade module 2 are located on the windward side of the grille 21, they are blown to abut against the grille 21. And in the closed position and covering the blade space 210, the oscillating blades 22 are further matched with the grating 21, and form a complete windward surface on the windward side, which can improve the rotational rotation efficiency, so that the novel can be driven by the wind. Together with the spindle 1, it is rotated in the running direction T.
而此時該轉軸1上方及靠左側的此兩葉片模組2因為旋轉至背風面，受到逆向風力流場所產生的一逆風風力之阻力，此兩葉片模組2的該等擺動葉片22進而被此逆風風力吹動而呈現開啟之透風狀態，此時該等擺動葉片22 位於該開啟位置，每一葉片空間210至少有局部部位不被擺動葉片22覆蓋而可透風，使逆向風可經由葉片空間210流入迎風側，從而能減少逆風阻力與逆向扭力，因此該兩葉片模組2呈較小之扭力。如此一來，本新型該三個葉片模組2整體所受到的扭力，可受到迎風面之順向風壓與逆風面之逆向風壓，此兩種通過軸心之風力壓差配合產生一用於推動本新型朝該運轉方向T轉動之風力。At this time, the two blade modules 2 above and to the left of the rotating shaft 1 are subjected to a windward wind force generated by the reverse wind flow field due to the rotation to the leeward surface, and the oscillating blades 22 of the two blade modules 2 are further The upwind wind blows to present an open, ventilated state, at which point the oscillating blades 22 In the open position, at least a partial portion of each blade space 210 is not covered by the oscillating blade 22 to be permeable to the wind, so that the reverse wind can flow into the windward side via the blade space 210, thereby reducing the upwind resistance and the reverse torque, and thus the two blade modes are Group 2 has a smaller torque. In this way, the torque of the three blade modules 2 of the present invention can be subjected to the reverse wind pressure of the windward surface and the reverse wind pressure of the windward surface, and the two winds are combined by the wind pressure of the shaft. To promote the wind of the present invention to rotate in the running direction T.
總結來說，本新型任一葉片模組2運轉至迎風面側時，其擺動葉片22受到迎風風力F1吹動而閉合，產生較大的順向扭力，而運轉至背風面側時，其擺動葉片22則可被逆向風力吹起掀開，以產生較小的逆向扭力。因此，順向風壓扣除逆向風壓後，使本新型整體之旋轉扭力較大而能提升風力之使用效率。In summary, when any of the blade modules 2 of the present invention is operated to the windward side, the oscillating blades 22 are blown by the windward wind F1 to close, generating a large forward torque, and when oscillating to the leeward side, the oscillating The blade 22 can then be blown apart by the reverse wind to produce a smaller reverse torque. Therefore, after the forward wind pressure is deducted from the reverse wind pressure, the overall rotational torque of the present invention is increased, and the use efficiency of the wind can be improved.
更進一步地，本新型於外圍處設有該等葉杯24，當其中一葉片模組2的該等葉杯24之凹陷的內表面241位於迎風面時，該葉片模組2受到該迎風風力F1吹動，使該葉片模組2的每一葉杯24呈現飽滿狀態，而流過該等外表面242之風的流動路徑大於流過該等內表面241的流動路徑。根據白努力定律，該等外表面242側的風壓較小，進而使該等葉杯24可被風力推動而朝該運轉方向T轉動，本新型整體因而以該轉軸1為旋轉中心軸而運轉。而且在運轉時，可能會產生一些逆向風力阻力，但由於本新型的該等葉杯24彼此之間為間隔設置，即，相鄰葉杯24之間存有空隙，因此逆向風可經相鄰葉杯24間的間隙流過，從 而能減少逆風阻力與逆向扭力。Further, the present invention is provided with the leaf cups 24 at the periphery. When the concave inner surface 241 of the leaf cups 24 of one of the blade modules 2 is located on the windward side, the blade module 2 receives the windward wind. F1 is blown to bring each of the vane cups 24 of the vane module 2 to a full state, and the flow path of the wind flowing through the outer surfaces 242 is greater than the flow path flowing through the inner surfaces 241. According to the white effort law, the wind pressure on the outer surface 242 side is small, so that the leaf cups 24 can be pushed by the wind to rotate in the running direction T, and the whole of the whole body is thus operated with the rotating shaft 1 as the central axis of rotation. . Moreover, during operation, some reverse wind resistance may occur, but since the vane cups 24 of the present invention are spaced apart from each other, that is, there is a gap between the adjacent vanes 24, the reverse wind may be adjacent to each other. The gap between the cups 24 flows through It can reduce headwind resistance and reverse torque.
而當任一葉片模組2轉動到非迎風面的位置時，其葉杯24則因為未直接受到迎風風力F1吹動，因而可能略微皺摺，直到葉片模組2又轉動到迎風位置時，其葉杯24即可再度被風吹動而呈現飽滿狀態。When any of the blade modules 2 is rotated to a position other than the windward surface, the leaf cup 24 may be slightly wrinkled because it is not directly blown by the windward wind F1 until the blade module 2 is rotated to the windward position. The leaf cup 24 can be again blown by the wind to be full.
值得一提的是，每一葉片模組2的擋風導流片27，能用於限制迎風面之風力流場的流動方向，可用於侷限風力流場以保留風力於該葉杯24的迎風側，使葉片模組2受到迎風風力F1推動而使運轉時能額外增加部分旋轉扭力。It is worth mentioning that the wind deflector 27 of each blade module 2 can be used to limit the flow direction of the wind flow field on the windward surface, and can be used to limit the wind flow field to retain the wind in the windward direction of the leaf cup 24. On the side, the blade module 2 is pushed by the windward wind F1 to increase the partial rotational torque during operation.
補充說明的是，通常在該轉軸1之徑向方向上，離該轉軸1越遠處受到的扭力與風力越大。所以在設計上，每一葉片模組2的該等擺動葉片22中，越遠離該轉軸1的該擺動葉片22的尺寸可以設計得越小。每一葉片模組2的該等葉杯24中，越遠離該轉軸1的該葉杯24的尺寸可以設計得越小。此外，本新型也可以視需求額外增加導流板，以求隨時導引風向。It is to be noted that, in the radial direction of the rotating shaft 1, the torque and the wind force which are received farther from the rotating shaft 1 are larger. Therefore, in design, in the oscillating blades 22 of each blade module 2, the smaller the size of the oscillating blades 22 away from the rotating shaft 1, the smaller the design. In the vane 24 of each vane module 2, the smaller the size of the vane 24 away from the rotating shaft 1, the smaller the design can be. In addition, the present invention can also additionally add baffles as needed to guide the wind direction at any time.
綜上所述，藉由每一葉片模組2同時設有該等擺動葉片22與葉杯24，而且該等葉杯24相對於該等擺動葉片22鄰近格柵21的外側214。由於越靠近裝置之徑向外圍的轉動速率較快、離心力也較大，故本新型的外圍處適合設置該等葉杯24來取代擺動葉片22，可承受較高轉速與較大離心力，從而避免【先前技術】所述之外圍處的擺動葉片較難以完全閉合的問題。透過該等擺動葉片22與葉杯 24之配合，進而提升風力運轉效率與扭力。本新型考慮實際使用時會面臨到的問題，並依據裝置不同部位所需的葉片結構特性，採用擺動葉片22與葉杯24此兩種不同的葉片結構，為一種創新、實用且效能佳之設計。In summary, each of the blade modules 2 is provided with the oscillating blades 22 and the leaf cups 24, and the leaf cups 24 are adjacent to the outer side 214 of the grille 21 with respect to the oscillating blades 22. Since the rotation speed of the radial periphery of the device is faster and the centrifugal force is larger, the peripheral cups of the present invention are suitable for providing the leaf cups 24 instead of the swinging blades 22, and can withstand higher rotation speed and large centrifugal force, thereby avoiding [Prior Art] The problem that the oscillating blade at the periphery is more difficult to completely close. Through the oscillating blades 22 and the leaf cup The cooperation of 24, thereby improving the wind operation efficiency and torque. The present invention considers the problems that will be encountered in actual use, and adopts two different blade structures, the oscillating blade 22 and the leaf cup 24, according to the blade structural characteristics required for different parts of the device, and is an innovative, practical and effective design.
參閱圖4，本新型風力葉片裝置之一第二實施例，與該第一實施例之結構大致相同，不同之處在於：本實施例的葉杯24是由硬質材料製成，主要運用於水利、海洋工程上，因此葉杯24無論是否受到風力或水力驅動而轉動時，皆呈現飽滿之半球殼狀。由於硬式材料的結構強度強，因此本實施例可以省略設置該第一實施例中的加強片25(圖3)與加強桿26(圖3)。Referring to FIG. 4, a second embodiment of the novel wind blade device is substantially the same as the structure of the first embodiment, except that the leaf cup 24 of the present embodiment is made of a hard material and is mainly used for water conservancy. In ocean engineering, the leaf cup 24 is full of hemispherical shell shape when rotated by wind or water. Since the structural strength of the hard material is strong, the reinforcing sheet 25 (Fig. 3) and the reinforcing rod 26 (Fig. 3) in the first embodiment can be omitted in the present embodiment.
本實施例的運作方式、運轉原理及達成功效，皆與該第一實施例相同，故不再說明。The operation mode, operation principle and achievement effect of the embodiment are the same as those of the first embodiment, and therefore will not be described.

In this case, the rotating shaft 1 extends up and down, and the first grating rods 211 also extend up and down, and the second grid rods 212 are The connecting end 221 and the swinging end 222 of the swinging blade 22 are vertically disposed, and the connecting end 221 of each of the swinging blades 22 is pivotally connected to one of the second gates 212, the swinging The end 222 is located on one side of the second grid 212 below the second gate 212 that is pivotally connected to the connecting end 221 .
綜合以上說明可知，本新型可運用於橫臥式裝置或直立式裝置，而且無論是橫臥式或直立式，該等葉杯24都可以採用軟式材料或硬式材料製成。In summary, the present invention can be applied to horizontal or vertical devices, and the cups 24 can be made of a soft material or a hard material, whether horizontal or vertical.
參閱圖5，本新型風力葉片裝置之一第三實施例 ，與該第一實施例的結構大致相同，不同的地方在於：本實施例的每一葉片模組2，靠近該格柵21的內側213的兩排擺動葉片22的尺寸(面積)較大，第三排擺動葉片22的尺寸較小。本實施例於第一排的空間中設置一個擺動葉片22，相同空間大小於第三排則可設置二個擺動葉片22；更進一步地，若再縮小擺動葉片22尺寸時，於每一個相同於第一排的空間大小中，可以設置八個擺動葉片22。該格柵21的第四排與第五排則設置葉杯24，且第五排葉杯24尺寸較小。在第四排的每一空間中設置一個葉杯24，於第五排的相同大小的每一空間中則可設置四個葉杯24。更進一步地，若再縮小葉杯24尺寸時，於每一個相同於第四排的空間中，可以設置十六個葉杯24。由於越靠近本新型該裝置之徑向外圍的轉動速率越大，故本實施例將靠近外圍處的葉杯24或擺動葉片22設計得較小，以求疏風較快，進而達到良好的運轉效率。Referring to FIG. 5, a third embodiment of the novel wind blade device The structure of the first embodiment is substantially the same as that of the first embodiment. In the blade module 2 of the embodiment, the size (area) of the two rows of swinging blades 22 adjacent to the inner side 213 of the grill 21 is large. The size of the third row of oscillating blades 22 is small. In this embodiment, one swinging blade 22 is disposed in the space of the first row, and two swinging blades 22 may be disposed in the third row in the same space size; further, if the size of the swinging blade 22 is further reduced, each is the same as Among the spatial sizes of the first row, eight oscillating blades 22 may be provided.

One leaf cup 24 is provided in each of the spaces of the fourth row, and four leaf cups 24 are provided in each of the same size of the fifth row. Further, if the size of the leaf cup 24 is further reduced, sixteen leaf cups 24 may be provided in each of the spaces identical to the fourth row. Since the rotation rate is closer to the radial periphery of the device of the present invention, the embodiment has a smaller design of the leaf cup 24 or the oscillating blade 22 near the periphery for faster wind separation and good operation. effectiveness.

Wherein, the inner backbone skeleton corresponds to the first row and the second row of the swinging blades 22, and the rod diameter needs to be designed to be the thickest, and must be supported from the axial center to the outermost ends of the swinging blades 22. The backbone skeleton on the middle side corresponds to the swinging blades 22 and the fourth row of the third row The leaf cups 24 of the row have a rod diameter smaller than that of the inner skeleton, as long as the third row of the swinging blades 22 and the fourth row of the cups 24 can be supported. The outer thin dry skeleton corresponds to the fifth row of cups 24, which extend from the middle side region to the outermost side of the grid 21 and must be able to support the fifth row of smaller size cups 24. And the rod diameter design of the inner backbone skeleton, the middle branch skeleton and the outer trunk skeleton must be at the minimum speed when the novel is rotated at a high speed, so that the skeleton member does not exhibit a bending phenomenon. .
