Description

Technical Field

[0001] The utility model relates to the technical field of power and material subject testing, in particular to an integral tension-compression type Hopkinson equipment shared platform. Background Art

[0002] At present, in view of the fact that gas is used as the medium in the Hopkinson bar experiment, pneumatic acceleration is simple to operate and has strong repeatability, becoming the universal power source for the Hopkinson bar experimental device. As the research on materials continues to develop towards higher strain rates, the experimental equipment is required to provide greater power. Increasing the gas pressure is one application method, but it also requires improving the safety operation standards of the entire experimental device, and the overall improvement of the experimental device is needed. In addition, in the process of mechanical research on materials, its compression and tensile properties alone are not enough. The mechanical properties of materials often lose their original function or even fail completely due to factors such as shape and structure. Therefore, it is necessary to build a multifunctional testing device that can not only study the tensile and compression properties of materials, but also the failure of material components and the expansion of mechanical properties.

[0003] Currently, independent Hopkinson bar experimental devices exist, but due to the rod diameter factor, the small-rod Hopkinson bar experimental device obtains an unstable state for the pulse value of the tensile and compressive component test data of the research material, especially the extended support required for the Hopkinson device experiment. Therefore, a shared platform for integral tension and compression Hopkinson devices is developed. Utility Model Content
