摘　　要：针对刚性轮对和独立轮对的不同特性,推导出完整的车辆动力学方程,研究二者相互组合转向架车辆动力学性能:稳定性和曲线通过性能。结果表明:独立轮对有助于提高车辆系统的稳定性;在较大曲线半径的线路上刚性轮对有助于改善车辆系统的曲线通过性能;二者作为导向轮,性能更好;受导向控制的独立轮对导向单元的导向性能更好。基于独立轮对,提出一种实用的导向控制方法,其结果表明具有良好的导向性能。According to the different characteristics of solid wheelsets and independently rotating wheelsets,the dynamic equation of the complete vehicle is derived,and the vehicle dynamics performance of the bogie combined with the two wheelsets is studied,i.e.,stability and curving performance.The results show that independently rotating wheelsets are benificial to enhance the stability of the vehicle system,and solid wheelsets are conducive to improving the curving performance of the vehicle system on the line of large curve radius.Both of the wheelsets are used as steering wheels with better performance,and the independently rotating wheelsets of steering controll has better curing performance.Based on independently rotating wheelsets,a practical steering control method is proposed,which has good steering performance.
