摘　　要：分析了悬挂式独轨车辆的结构特点,并应用软件Simpack建立车辆多体模型,探讨悬挂式独轨车辆稳定性、安全性、平稳性性能评判方法。通过仿真分析不同载客量悬挂式独轨车辆在曲线及横风作用下的响应表明,悬挂车体的横移量及走行轮、导向轮的载荷是车辆的动力学性能重要评判参数,且有相应的限值。讨论导向轮合理的预压力大小的确定方法,并给出计算模型的初步预压力的具体数值。Structure characteristics of hanged-type monorail vehicle was analyzed, and based on SIMPACK software, criteria of the stability, safety and ride comfort for this type monorail vehicle was discussed. Simulation analysis with different passenger loads in condition of curve and crosswind showed that the lateral displacement of car body and the loads of driving tires and steering tires was an important criteria parameter with limited value. The method to determine a proper pre-pressure for steering tire was discussed and the value of initial press for steering tires for the simulated vehicle was given.
