Description
Technical field
The present invention relates to material testing apparatus field, the loading equipemtn of a kind of rigidity test and using method thereof.
Background technology
The rigidity test of material is important indicator for the material property of workpiece.Material is likely to occur different deformation under different load, thus shows different rigidity characteristics.More existing test equipment are material to be continuously applied to the load being gradually increased, and measure the deflection of generation during the course.Due to dynamic and the instantaneity of measurement of load variations, this mode easily causes measurement error.And in the equipment for fixed value formula imposed load, due to the discreteness of fixed value, therefore, it is difficult to obtain the some position performance of expected value at any time.And, during the holding of fixed value, it is susceptible to load slight fluctuations, thus causes measurement error.And though some equipment ensure that certainty of measurement, relatively costly, maintenance work is complicated.
Summary of the invention
It is an object of the invention to provide loading equipemtn and the using method thereof of a kind of rigidity test, it is possible to solve the problems of the prior art.
