Description
Technical field
Present invention relates particularly to material mechanical performance test and characterization technique field, be specifically related to a kind of battery film material high-speed stretch tester.
Background technology
Lightweighting materials collision dynamics behavior characterizes and depends on different stress states, mainly has stretching, compression, shearing, bending etc..For research material mechanical characteristic under different stress, it is necessary to carry out the test under different strain rate.Material static test (strain rate scope is at 0.001/s-1/s) generally completes on electronic universal tester, and MATERIALS ' DYNAMIC test (strain rate scope is at 1/s-1000/s) generally completes on mid strain rate testing machine and high speed tensile test machine.
Due to battery film material thinner thickness, flexible, if being clamped directly on testing machine chuck, it is easy to cause torsion thus sample itself is caused damage, primary stress and deformation can be produced, affect test accuracy simultaneously.Meanwhile, because sample fracture load is less, and the transducer range scope that testing machine carries is relatively big, measurement result inaccuracy.Battery film material is clamped it is thus desirable to design special assay device and measures so that sample is not by unbalance loading, thus ensureing the accuracy of test result.
