基于有限元法的动车组行李架优化分析

Optimization of EMU Luggage Rack Applicability Based on Finite Element Calculation

为解决现有高速动车组行李架玻璃承载面板易破损的安全隐患,利用有限元方法对玻璃承载面板和聚碳酸酯承载面板这两种行李架的应力和位移进行比较分析,寻找聚碳酸酯承载面板位移变化的原因和优化措施。结合动车组行李架内部结构分析,提出了行李架结构优化建议,为承载面板由玻璃板更改为聚碳酸酯板的优化措施提供技术论证。

In order to reduce damage risks of the widely used glass EMU luggage rack,the stresses and displacements of glass luggage rack and polycarbonate bearing plate rack(PBPR)are compared and analyzed,the main reasons for the displacement of PBPR and improvement measures are discussed.On this basis,combined with the internal structure analysis of EMU luggage rack,an optimization scheme is proposed to provide technical demonstration for PBPR that will replace the glass bearing panel.
