摘　　要：运用多体系统动力学软件SIMPACK建立了铰接式直接驱动转向架的车辆系统动力学模型,通过仿真计算分析了三角杆纵向刚度和横向刚度与车辆临界速度的关系,并对二系悬挂垂向刚度和垂向阻尼的参数进行了优选.最后分析了整车曲线通过性,结果表明直接驱动转向架具有良好的动力学性能,能满足运行的需要.Vehicle system dynamic models of the direct drive bogie were established based on SIMPACK. With the simulation calculation, the relationship between non-critical speed and the longitudinal stiffness and lateral stiffness of the triangle rod was analyzed, and the main parameters were selected for the secondary suspension system of the direct drive bogie. The passing curve capability of the vehicle＇s was finally analyzed. The result shows excellent dynamic performances which could meet the need of running.
