Design and finite element analysis of shaking table for fatigue test of high speed train transmission system

With large scale increases of the train speed, it is of great practical significance to develop a fatigue test stand for high-speed train's transmission system. 3-DOF (three degree-of-freedom) electro-hydraulic shaking table for high-speed train's transmission system fatigue test is designed and its three dimensional mathematical model is established in this paper. In addition, static analysis and modal analysis of this shaking table are carried out by finite element analysis software. The results show the rationality of our mechanism design. The above research work lays the foundation for structural improvement and optimum design of shaking table.
