【Abstract】 The load condition of linear eddy current braking device of high-speed train is complex. For the safety of engineering application, the structural strength of the product should be comprehensively analyzed. By analyzing the structural characteristics and load conditions, strength calculations under various typical working conditions are carried out using finite element software. Vibration and shock tests and bench test methods are studied, and strength simulations are compared with test results. The research results show that the current test equipment cannot meet the requirements of Category 3 vibration and shock tests for eddy current braking devices.The structural integrity of the product can be assessed by a combination of Category 2 vibration and shock tests of the entire machine and strength tests of the main frame.The strength calculation of eddy current braking device is consistent with the test results, which verifies the effectiveness of the strength calculation and test of the product structure. The calculation results of static strength and fatigue strength of eddy current braking device under various working conditions meet the requirements of relevant standards, and the developed products have passed the relevant test verification.更多还原
