跨坐式单轨车辆走行轮轮辋优化设计

跨坐式单轨车辆的转向架结构与其他轨道交通车辆不同,其转向架走行机理差异是关键。为此,从单轨列车轮辋与轮芯的摩擦连接行为、摩擦特性研究入手,将走行轮轮辋圆锥斜面椎角由28°优化为27°。通过静扭试验,验证了优化后的27°轮辋传动性能优于28°轮辋。运用Hyperwoks有限元软件计算分析,结果表明优化过后的轮辋刚度与强度均满足设计要求。

Structural Optimization of Walking Wheel Rim Design for Straddle-type Monorail Vehicle

The important difference between straddle-type monorail and the subway system is the bogie structure,the key discrepancy of which is the bogie direction mechanism.Therefore,the optimization of walking wheel is studied firstly from the perspective of the friction and connection behavior between the wheel rim and wheel core,the conical surface angle of walking wheel rim is optimized from 28 degrees to 27.Through static torsion test,the 27 degrees rim has displayed higher drive performance than the 28 degrees rim.Then the finite element analysis software Hyperwoks is used to analyze the straddle-type monorail rim,and the results indicate that the optimized stiffness and strength of the walking wheel rim can meet the design requirements.
