摘要: 为了提高地铁车辆转向架的曲线通过安全性，以及降低轮轨磨耗，文章阐述了几种径向转向架的导向原理，并基于多体系统动力学理论建立了传统、自导向、迫导向和主动径向转向架四种地铁车辆动力学模型，对比分析了不同转向架车辆的导向性能。研究结果表明，常规径向转向架可以降低轮轨冲角和轮轨磨耗，但在小半径曲线下径向效果不佳；主动径向转向架可以显著改善轮轨冲角和轮轨磨耗，可以兼顾各种曲线工况，取得远优于传统转向架以及常规径向转向架的导向效果。
Abstract: To improve the running safety during curve passing and reduce the wheel-rail wear for metro vehicle bogies, the steering principle of radial bogies was described. Based on the theory of mul-ti-body dynamic system, four kinds of dynamic models for metro vehicles with traditional bogie, self-steering bogie, forced-steering bogie and active-steering bogie were developed respectively, and their steering performances were compared and analyzed. The results showed that conven-tional radial bogies could reduce the wheel-rail incidence angle and wheel-rail wear, however, its radial effect is unsatisfactory in the case of small radius curves. The active radial bogie could significantly improve the wheel-rail incidence angle and wheel-rail wear in various curve conditions and acquire a steering effect far superior to traditional bogies and conventional radial bogies.
