How to determine the good or bad design of hydraulic fixture?
There are more processes of hydraulic fixture design, including sample making and testing, specimen stretching and compression, etc., which can be tested from the fixture use condition and test process.
The sample making test of fixture design, tensile and compression of specimen are carried out separately (i.e. tensile and compression are carried out with different fixtures), and the specimen can be subjected to both tensile and compressive tests in the same test
Hydraulic fixture design is determined by the following methods.
1, the use of fixture simplicity, safety is not reliable;
2, whether the clamping stability, can not have slippage phenomenon;
3, to do the test process, the specimen break point is good, the data dispersion is small.
There is no single way to judge the hydraulic jig, the above three points are only the basic judgment, in addition, it is also necessary to combine the actual use of the situation. Hydraulic fixture manufacturers must strictly control the quality when designing and producing, so as to ensure that the fixture produced can be widely used in production.
