Dynamic fatigue testing machine
The first domestic high-speed rail pantograph three-degree-of-freedom dynamic test rig, which can simulate the dynamic working conditions of the high-speed rail pantograph in the horizontal, vertical and vertical directions. The acceleration of lateral movement is ≥10g, and the acceleration of longitudinal and vertical movement is ≥30g. Various extreme working conditions of pantograph. Before the completion of the test rig, the pantograph test only had a dynamic performance test in one vertical direction.
