Description
Technical field
The present invention relates to a kind of power and moment measurement instrument.
Background technology
At present, it is widely applied in test and engineering practice along with being used for the power of the measuring measuring instrument with moment, has
Close measuring instrument precision under more complicated even adverse circumstances and robustness is particularly important for measuring instrument.
In ship model rolling experiment, experimental enviroment is more complicated, and the number of times of experiment with measuring and precision have
Certain requirement.If general measuring instrument can not ensure precision and durability under this complex environment, then can be to the knot of test
Really, fussy degree and cost have impact in various degree.
Summary of the invention
It is an object of the invention to provide and remain able to ensure required precision under complex environment engineering, experimental enviroment,
And ship model cross force and the horizontal righting moment measuring instrument of repeatedly circulation, long-time measurement demand can be undertaken.
The object of the present invention is achieved like this:
Ship model cross force of the present invention and horizontal righting moment measuring instrument, is characterized in that: include main sliding unit, secondary cunning

Present invention have an advantage that
1, ship model heeling experiment manufacture it is specifically designed for so that its ease in use and directly perceived in Ship model test.
2, fully taken into account the complexity of experimental enviroment in Ship model test, designed targetedly for its precision
With the guarantee that reliability has abundance.
Accompanying drawing explanation
Fig. 1 is the front view of the present invention；
Fig. 2 is the three-dimensional view of the present invention；
Fig. 3 is 5 ° of interval sub-degree angle adjustment plate in angle adjusting；
Fig. 4 is 10 ° of interval sub-degree angle adjustment plate in angle adjusting.
Detailed description of the invention
Illustrate below in conjunction with the accompanying drawings and the present invention be described in more detail:
In conjunction with Fig. 1-4, the assay device of the present invention is by angle adjusting 6, load carrying unit 5, main sliding unit 4, secondary cunning
The part composition such as moving cell 2, gravity dumping unit 3.Whole device is fixed on seaworthiness instrument 1 by upper lower installation board, and height can
Could be adjusted to tackle the Ship model test of different size.Main sliding unit 4 is direct with seaworthiness instrument 1 by upper lower installation board
Being connected, below secondary sliding unit 2, connection gravity dumping unit 3 be arranged in parallel with main sliding unit 4 and is connected with seaworthiness instrument 1.
Below main sliding unit 4, one end connects load carrying unit 5, one end connection angle adjustment unit 6 below load carrying unit 5.Wherein, lead,
Secondary sliding unit main parts size is the experimental enviroment of complexity and is designed, and when sliding up and down, frictional resistance is less, is difficult to
Damage, it is sufficient to realize long-time repeatedly cyclic test.
The present invention is that ship model heeling experiment is designed to be manufactured, and according to the character tested to overall structure and each zero
Part has carried out designing targetedly, and its main force cell is six component balance, can carry out X, Y, Z, Mx, My, Mz etc. six
The measurement of individual component.Wherein, Z value is in routine test measured resistance (unit: KG), and Mz is the required heeling moment surveyed
(unit: KG M).Angle of Heel 5 ° during ship model heeling experiment, 10 °, 15 °, 20 °, 25 °, 30 °, 35 °, 40 °, 45 ° adjustable, ship model
Pitch orientation maximum attitude angle is less than 20 °, tests maximal rate less than 10m/s in ship model hydrostatic.
Propagation model cross force territory horizontal righting moment measuring instrument designed by the present invention, is used for measuring ship model heel
Cross force produced by model heel and the measuring instrument of horizontal righting moment in test
According to Fig. 1, the seaworthiness instrument 1 contained by the present invention, secondary sliding unit 2, gravity dumping unit 3, main sliding unit 4,
Load carrying unit 5, angle adjusting 6, assemble the most in order according to drawing further according to 2, after assembling, check that primary and secondary is slided
Two light distance between axles of unit, it is desirable to error is ± 0.05mm.Bearing is coated with grease before being inserted in optical axis, it is ensured that slide flexibly.
Determine the spacing distance of main sliding unit according to ship model height of C.G., after determining by upper lower installation board clamp stud and
Optical axis shaft stools etc. are locked.
Determine the range of movement of load carrying unit according to ship model motion heave etc. in water, so determine load carrying unit, from
The length etc. of cable wire is connected between weight unloading unit.Connect cable wire and carry out guide and limit by the pulley on upper mounting plate, middle
Buffer spring is set.
Weighing load carrying unit (comprising balance, angle adjusting) with electronics push-and-pull scale, weight is 30.5Kg.Counterweight list
Individual heavy 8Kg, installs four pieces of 32Kg altogether, therefore increases counterweight 1.5Kg on load carrying unit upper junction plate, reach balance, make load list
Unit's gravity dumping.
Lower rock shaft is fixed at ship model position of centre of gravity, is connected with heeling experiment auxiliary device by central shaft 2.Connect the day before yesterday
Put down and carry out Zero calibration, be acquired again after connection, record initial value.
According to Fig. 3,4 angle adjustment plates have two kinds, and one realizes 5 ° of interval indexing, and one realizes 10 ° of interval indexing.
If occurring in process of the test, ship model dolphin or shake should be stopped immediately, and anti-locking apparatus damages.Wavegoing model test
Towed speed is less than 5m/s, and the response of speed the highest device can affect the accuracy of test data more slowly.
