跨座式单轨转向架构架结构分析与优化

Structural Analysis and Optimization of Bogie for Straddle Type Monorail Vehicle Based on Optistruct

转向架作为轨道车辆的重要组成部分,起着牵引行走和制动等重要作用,是决定列车运行安全和动力学性能最为关键的组成部分。利用CATIA软件建立了新转向架构架的三维模型;利用HyperWorks软件建立了新转向架构架的有限元模型。结合跨座式单轨车辆转向架构架典型受力工况,采用有限元方法,对新转向架构架进行尺寸优化详细设计、静强度分析和模态分析。优化分析结果显示,新转向架构架在满足结构强度刚度要求的同时也达到了轻量化的效果,同时构架的动态特性比较好。

Bogie regarded as a key part in rolling stock is acted on important functian in brake rigging system. Using CATIA software to establish the 3D model of the new bogie, and HyperWorks to establish the finite element model of the new bogie. Combined with the typical stress conditions of straddled-type monorail vehicle bogie frame,it takes the size optimization, static strength analysis and modal analysis on the new bogie frame based on the finite element method. The optimization and analysis results show that the new bogie is good at both structural strength and light weight. A good optimization result is realized; at the same time the frame has the better dynamic characteristics.
