Problems solved by technology
Due to the low strength and rigidity of some parts in the mechanical structure, there will be bending, fracture, or failure to meet the use requirements caused by internal defects during use, which may cause the machine to fail or even cause casualties. For these parts It is necessary to carry out fatigue tests on components to verify whether these components can meet the requirements of use, and provide better test data for the design of components, and improve the strength and rigidity of components

Description
technical field [0001] The invention relates to a fatigue test device for omnidirectional vehicle connectors, which belongs to the field of vehicle engineering. Background technique [0002] With the rapid development of modern industry, all walks of life have continuously improved the performance requirements of mechanical structure parts. In order to meet the requirements of high performance, the produced mechanical structural parts need to be tested to verify whether they meet the required performance requirements. Due to the low strength and rigidity of some parts in the mechanical structure, there will be bending, fracture, or failure to meet the use requirements caused by internal defects during use, which may cause the machine to fail or even cause casualties. For these parts It is necessary to carry out fatigue tests on components to verify whether these components can meet the requirements of use, and provide better test data for the design of components, and impro...
