Description
Technical field
The present invention relates to material testing apparatus field, be specially a kind of material stiffness test charger and user thereof
Method.
Background technology
The rigidity test of material is important indicator for the material property of workpiece.Material may go out under different load
Existing different deformation, thus show different rigidity characteristics.More existing test equipment be for material be continuously applied by
Cumulative big load, 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, because of
This some position performance being difficult to obtain expected value at any time.And, during the holding of fixed value, it is susceptible to load slight fluctuations,
Thus cause measurement error.And though some equipment ensure that certainty of measurement, relatively costly, maintenance work is multiple
Miscellaneous.
