Structural Analysis And Optimum Design Of High-Speed Train Sliding-Plug Door

Sliding-plug door is commonly fitted on high-train to meet the strict requirement caused by the aerodynamic pressure. Though there are many difficulties found in design and manufacture of sliding-plug door, analysis and experimental research about them are in rare number. The structural analysis and design optimization, which will facilitate and improve the design of sliding-plug door, is present in this paper. The analysis in this paper have been verified by experimentFirstly, the structure and mechanical characteristics of sliding-plug door are described in this paper. Secondly, on the base of the study of the work condition and limited load, the dynamic load-time curve is created. And then the finite element model of sliding-plug door is built by using material equivalent. This paper also present simulations of the door under various specified load.The method of numerical simulation proposed in this paper is verified by a series of experiments.The method of the design optimization is investigated in this paper, and a design optimum example of sliding-plug door is offered.
