Disassembly sequence optimization for automotive product based on probabilistic planning method

Disassembly is a systematic method for separating a product into its constituent parts. Based on the uncertain feature of disassembly process, combined with the defined probability transmission rules of different constrain nodes, the optimal disassembly sequence is determined by the probabilistic planning method. Simultaneously, a simple example is presented to test the proposed probabilistic planning method.

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 trains transmission system. 3-DOF (three degree-of-freedom) electro-hydraulic shaking table for high-speed trains 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.
