Description

資料を恒温・恒湿の環境条件下で、荷重を次第に増大させ破壊に至るまで試験する引張破壊試験装置、或いは所定の湿度・温度で一定荷重をかけ長時間引張試験を行いクリープ量を変位測定する引張クリープ試験機。   Tensile fracture test equipment that tests materials until they are destroyed by increasing the load under constant environmental conditions of constant temperature and humidity, or measuring the amount of creep by performing a long-term tensile test at a predetermined humidity and temperature. Tensile creep testing machine.

従来、図1に示すごとく、試験室内にある試料の一端を資料取付け台に固定し、他端を引張棒に固定され、エアーシリンダーの引張方向荷重で単純に引張り、その時の変位と引張り荷重を測定するという破壊試験機が一般的であった。
また、図２に示すごとく、レバーの支点を錘位置と荷重点の間に設け、引張り方向荷重が中間棒にかかるようにし、所定の環境下で一定の引張り荷重でのクリープ(変位、変形）量を計測する引張試験機などが一般的である。 Conventionally, as shown in Fig. 1, one end of the sample in the test chamber is fixed to the data mounting base, the other end is fixed to the tension rod, and simply pulled by the load in the air cylinder's tensile direction, and the displacement and tensile load at that time are measured. Destructive testing machines that measure are common.
In addition, as shown in FIG. 2, a lever fulcrum is provided between the weight position and the load point so that a tensile load is applied to the intermediate rod, and creep (displacement, deformation) with a constant tensile load in a given environment is performed. A tensile tester that measures the amount is common.

通常これらの試験機の試験室を所定の温度まで昇温するため、試験室の周囲特に、底部をボディヒータ等で加熱する必要がある。この昇温により、試験室を構成する筐体は数百μmの熱歪を生じ、変位センサーはこの熱歪を資料の変形と判断して計測することとなる。勿論、筐体の熱歪のみならず、資料を取り付ける台やチャック引張棒の熱歪も合算されるため変形量の精度がはなはだしく落ちるという欠点があった。
特に、100℃以上の高温を得るためには試験室の底部をボディヒータで集中的に加熱する必要があるが、底部は加熱温度に比例して凸形に大きく変形するため、資料の取り付け台は上下に数百μm変位することは実験的に明らかにされている。
特に、高温での引張クリープ試験時に高精度に変形量を測定する場合には、熱歪は精度維持の上で大きな問題となる。
特開平07-035665 Usually, in order to raise the temperature of the test chamber of these test machines to a predetermined temperature, it is necessary to heat the periphery of the test chamber, in particular, the bottom with a body heater or the like. Due to this temperature rise, the housing constituting the test chamber generates a thermal strain of several hundreds μm, and the displacement sensor measures the thermal strain by determining that the thermal strain is a deformation of the material. Of course, not only the thermal strain of the casing but also the thermal strain of the table on which the material is attached and the chuck tension bar are added together, so that there is a drawback in that the accuracy of the deformation is drastically reduced.
In particular, in order to obtain a high temperature of 100 ° C or higher, it is necessary to intensively heat the bottom of the test chamber with a body heater, but the bottom is greatly deformed into a convex shape in proportion to the heating temperature. It has been empirically revealed that can be displaced by several hundred μm up and down.
In particular, when measuring the amount of deformation with high accuracy during a tensile creep test at a high temperature, thermal strain becomes a major problem in maintaining accuracy.
JP 07-035665

資料を高温・高湿下で引張破壊試験或いは引張クリープ試験を行う装置において、筐体の加熱による熱歪の影響を受けずに、資料自体の引張時の変形・歪のみを高精度で測定できる装置を提供する。このために、特に、熱歪を受けやすい加熱部分である試験室底部に試料の固定端を取り付けず、筐体の上端部を基準に資料の変位を測定する構成とする必要がある。   In a device that conducts tensile fracture tests or tensile creep tests on materials at high temperatures and high humidity, it can measure only the deformation and strain of the materials themselves when they are pulled without being affected by the thermal strain caused by heating of the housing. Providing equipment. For this reason, in particular, it is necessary not to attach the fixed end of the sample to the bottom of the test chamber, which is a heated part that is easily subjected to thermal strain, but to measure the displacement of the material with reference to the upper end of the housing.

加圧機2は引張ではなく圧縮方向に加圧する構成とする。圧縮荷重を測定するロードセル5を含む荷重伝達部材7は低膨張係数材料であり、弾性部材８を介して試験室18に延長され、試料の一端を取り付けるためのチャッキング１０を先端に有している。また、前記資料の他端を取り付けるチャッキング手段9はヒンジ12で筐体１７に固定される。尚、変位センサ11は計測手段６で前記荷重伝達部材７に適時固定できるように構成されており、加圧機２の圧縮荷重が作用した際の、資料１３のｙ軸方向に伸びる変位量を筐体１７の上部壁を基準に正確に測定する。   The pressurizer 2 is configured to pressurize in the compression direction instead of tension. The load transmission member 7 including the load cell 5 for measuring the compressive load is a low expansion coefficient material, and is extended to the test chamber 18 through the elastic member 8 and has a chucking 10 for attaching one end of the sample at the tip. Yes. The chucking means 9 for attaching the other end of the material is fixed to the housing 17 by a hinge 12. The displacement sensor 11 is configured so that it can be fixed to the load transmission member 7 by the measuring means 6 in a timely manner, and the displacement amount of the material 13 extending in the y-axis direction when the compression load of the pressurizer 2 is applied. Accurate measurement based on the upper wall of the body 17.

このような構成とすることで、試験室昇温のためボディヒータ16で加熱されて、筐体１７の底部が変形しても全くその影響を受けない。更に、資料13の他端は筐体17の上部と一体のヒンジ12で固定されたチャッキング9に取り付けられる構成となっているため、筐体17の上部で計測される変位センサ11には筐体17のｙ軸方向の熱歪による誤差は殆ど生じない。
尚、荷重伝達部材7自体も低熱膨張係数の材料で製作されることで、試験機内温度の昇温時でも熱歪による変位誤差を最小限に抑えることが可能となる。 With such a configuration, even if the bottom portion of the casing 17 is deformed by being heated by the body heater 16 to raise the temperature of the test chamber, it is not affected at all. Further, since the other end of the material 13 is attached to the chucking 9 fixed by the hinge 12 integrated with the upper part of the casing 17, the displacement sensor 11 measured at the upper part of the casing 17 is not included in the casing. There is almost no error due to thermal distortion of the body 17 in the y-axis direction.
The load transmission member 7 itself is also made of a material having a low coefficient of thermal expansion, so that a displacement error due to thermal strain can be minimized even when the temperature inside the testing machine is raised.

恒温・恒湿の条件下で荷重を加え引張試験を行うとか長時間定荷重で引張試験を行い、高精度に変位を計測する引張試験機の実施例に関し以下説明を行う。   An example of a tensile testing machine that performs a tensile test by applying a load under constant temperature and humidity conditions or performing a tensile test at a constant load for a long time and measuring displacement with high accuracy will be described below.

図3に実施例1を示す。加圧機2は圧縮荷重をかけるようにｙ軸方向にねじが形成されたロッド3を有しており、該ロッド3にはｙ軸距離を調整可能な調整ねじ4がねじ勘合されている。該ロッド3の下端部はロードセル5のセンシング部分と常に接触するように手動で調整ねじ4で調整される構成となっている。該ロードセル5は変位計測手段6と試験機室18に延長する荷重伝達部材7と同軸上に固定されている。
前記変位計測手段6には変位センサ11が荷重伝達部材7に平行に摺動可能に取り付けられ、変位計測のステップでは前記荷重伝達部材7にしっかりとねじ固定される構成となっている。また、前記変位計測手段6と筐体17上部間に弾性手段8が配置され、前記、荷重系の自重が不本意に資料13に作用しないように常に上方向へ押し上げている。更に、試料の一端を取り付けるためのチャッキング１０が前記荷重伝達部材7の下端に設けられており、前記資料13の他端を取り付けるチャッキング手段9はヒンジ12で筐体１７に固定される構成となっている。したがって、荷重伝達部材7に圧縮荷重がかかると資料13は上下に引張られることとなる。そして、資料13の荷重による変位は変位センサ11により正確に計測される。
該変位センサー11はセンシング先端が前記筐体17の上部に接しているため、該筐体17の上部が熱歪などで変形してもヒンジ12でとめられたチャッキング9部分と前記センシングが同期するため変位センサー11は熱歪の影響を受けない。
A矢視には資料13の取付け詳細がしめされている。資料13の下部と前記荷重伝達部材７の下部はビス15でチャッキングされ、資料13の上端部とチャッキング9はビス14でチャッキングされる構成となっている。尚、試験機室18には所定の湿度・温度を供給する入り口とその出口が設けられており、筐体17の下部には試験室を加温するためのヒータ16が配置されている。該ヒータによる加熱では筐体17の底部が凸形に熱変形するが、この影響は測定系のどこにも現れない構成となっているのが特徴である。 Example 1 is shown in FIG. The pressurizer 2 has a rod 3 formed with a screw in the y-axis direction so as to apply a compressive load, and an adjusting screw 4 capable of adjusting the y-axis distance is screwed to the rod 3. The lower end of the rod 3 is manually adjusted with the adjusting screw 4 so as to be always in contact with the sensing portion of the load cell 5. The load cell 5 is fixed on the same axis as the displacement measuring means 6 and the load transmitting member 7 extending to the testing machine chamber 18.
A displacement sensor 11 is attached to the displacement measuring means 6 so as to be slidable in parallel with the load transmitting member 7, and is configured to be firmly screwed to the load transmitting member 7 in a displacement measuring step. Further, an elastic means 8 is arranged between the displacement measuring means 6 and the upper part of the casing 17, and is always pushed upward so that the weight of the load system does not inadvertently act on the material 13. Further, a chucking 10 for attaching one end of the sample is provided at the lower end of the load transmitting member 7, and the chucking means 9 for attaching the other end of the material 13 is fixed to the casing 17 by a hinge 12. It has become. Accordingly, when a compressive load is applied to the load transmitting member 7, the material 13 is pulled up and down. The displacement of the material 13 due to the load is accurately measured by the displacement sensor 11.
Since the sensing tip of the displacement sensor 11 is in contact with the upper part of the casing 17, the sensing is synchronized with the chucking 9 portion stopped by the hinge 12 even if the upper part of the casing 17 is deformed due to thermal strain or the like. Therefore, the displacement sensor 11 is not affected by thermal strain.
The mounting details of document 13 are shown in the direction of arrow A. The lower part of the material 13 and the lower part of the load transmission member 7 are chucked with a screw 15, and the upper end part of the material 13 and the chucking 9 are chucked with a screw 14. Note that an inlet for supplying predetermined humidity and temperature and an outlet for supplying predetermined humidity and temperature are provided in the testing machine room 18, and a heater 16 for heating the testing room is disposed at the lower part of the casing 17. Although the bottom of the casing 17 is thermally deformed into a convex shape by heating with the heater, this effect is characterized in that the influence does not appear anywhere in the measurement system.

図4に他の実施例を示す。荷重系は基本的には錘18、レバー20、荷重ON-OFFカム19および支点21で構成されている。レバー20の支点21の位置により錘荷重が増幅される。また、荷重ON-OFFカム19により荷重点にある調整ロッド3に作用する圧縮荷重のON-OFFの切り替えができる構成となっている。該調整ロッド3にはｙ軸距離を調整可能な調整ねじ4がねじ勘合されている。該ロッドの下端部はロードセル5のセンシング部分と常に接触するように手動で調整ねじ4で調整される構成となっている。該ロードセル5は変位計測手段6と試験機室18に延長する荷重伝達部材7と同軸上に固定されている。
前記変位計測手段6には変位センサ11が荷重伝達部材7に平行に摺動可能に取り付けられ、変位計測のステップでは前記荷重伝達部材7にしかりと固定される構成となっている。また、前記変位計測手段6と筐体17上部間に弾性手段8が配置され、前記、荷重系の自重が不本意に資料13に作用しないように常に上方向へ押し上げている。更に、試料の一端を取り付けるためのチャッキング１０が前記荷重伝達部材の下端に設けられており、前記資料13の他端を取り付けるチャッキング手段9はヒンジ12で筐体１７に固定される構成となっている。したがって、荷重伝達部材7に圧縮荷重がかかると資料13は上下に引張られることとなる。そして、資料13の荷重による変位は変位センサ11により正確に計測される。
該変位センサー11はセンシング先端が前記筐体17の上部に接しているため、該筐体17の上部が熱歪などで変形してもヒンジ12でとめられたチャッキング9部分と前記センシングが同期するため変位センサー11は熱歪の影響を受けない。
A矢視には資料13の取付け詳細がしめされている。資料13の下部と前記荷重伝達部材７の下部はビス15でチャッキングされ、資料13の上端部とチャッキング9はビス14でチャッキングされる構成となっている。尚、試験機室18には所定の湿度・温度を供給する入り口とその出口が設けられており、筐体17の下部には試験室を加温するためのヒータ16が配置されている。該ヒータによる加熱では筐体17の底部が凸形に熱変形するが、この影響は測定系のどこにも現れない構成となっているのが特徴である。 FIG. 4 shows another embodiment. The load system basically includes a weight 18, a lever 20, a load ON-OFF cam 19 and a fulcrum 21. The weight load is amplified by the position of the fulcrum 21 of the lever 20. In addition, the load ON-OFF cam 19 can be switched ON / OFF of the compression load acting on the adjustment rod 3 at the load point. The adjusting rod 3 is screwed with an adjusting screw 4 capable of adjusting the y-axis distance. The lower end portion of the rod is manually adjusted with the adjusting screw 4 so as to always contact the sensing portion of the load cell 5. The load cell 5 is fixed on the same axis as the displacement measuring means 6 and the load transmitting member 7 extending to the testing machine room 18.
A displacement sensor 11 is attached to the displacement measuring means 6 so as to be slidable in parallel with the load transmitting member 7 and is fixed to the load transmitting member 7 in a displacement measuring step. Further, an elastic means 8 is arranged between the displacement measuring means 6 and the upper part of the casing 17 and is always pushed upward so that the weight of the load system does not inadvertently act on the material 13. Further, a chucking 10 for attaching one end of the sample is provided at the lower end of the load transmitting member, and the chucking means 9 for attaching the other end of the material 13 is fixed to the casing 17 by a hinge 12. It has become. Accordingly, when a compressive load is applied to the load transmitting member 7, the material 13 is pulled up and down. The displacement of the material 13 due to the load is accurately measured by the displacement sensor 11.
Since the sensing tip of the displacement sensor 11 is in contact with the upper part of the casing 17, the sensing is synchronized with the chucking 9 portion stopped by the hinge 12 even if the upper part of the casing 17 is deformed by thermal strain or the like. Therefore, the displacement sensor 11 is not affected by thermal strain.
The mounting details of document 13 are shown in the direction of arrow A. The lower part of the material 13 and the lower part of the load transmission member 7 are chucked with a screw 15, and the upper end part of the material 13 and the chucking 9 are chucked with a screw 14. The test chamber 18 is provided with an inlet for supplying predetermined humidity and temperature and an outlet thereof, and a heater 16 for heating the test chamber is disposed at the lower portion of the casing 17. Heating by the heater causes the bottom portion of the casing 17 to be thermally deformed into a convex shape, and this effect is characterized in that it does not appear anywhere in the measurement system.

圧縮方向に荷重をかけることで引張試験が行えることから、筐体内部の資料を取り付ける部品のみ入れ替えることで、圧縮破壊・クリープ試験機に容易に変更可能となる。   Since a tensile test can be performed by applying a load in the compression direction, it is possible to easily change to a compression fracture / creep tester by replacing only the parts to which the data inside the housing is attached.
