摘　　要：纵观国内外轻轨车的发展,分析了几种经典轻轨车辆结构型式的曲线通过问题。给出了一种将行星差速器与横向耦合相结合的独立轮对结构,研究了该结构的传动参数配置。分析基于转速差为控制目标的主动控制方式,最后通过动力学仿真对比分析3种轮对结构的直线复位能力和曲线通过性能。Throughout the development of light rail transit in China and abroad,the structural elevation of several mainstream light rail transit is analyzed.A kind of independent wheels pair structure combining planetary differential with shaft bridge was studied by its parameter configuration.This paper analyzes the active control method based on the difference angle of the left and right wheels.Finally,the capacity to restoring on tangent tracks and curing performances of the three wheelset structures are compared and analyzed by dynamic analysis.
