摘　　要：采用１７个自由度的客车横向振动非线性模型，模拟了轨道方向不平顺的随机波形，并利用键图法对准高速客车横向平稳性进行了计算。文中还分析了悬挂参数对车辆横向平稳性的影响，根据分析结果优选出合理的车辆匹配参数。The non-linear lateral vibration passenger car niodel with 17 degrees of freedom is applied,the random wavepattern of the track irregularity in the track direction is simulated ,and the lateral stability of quasi-high speed passenger carsis calculated with the method of bond graph. In this paper.the effects of suspension parameters on the lateral stability of carsare also analyzed. On the basis of the analysis results.the reasonable matching parameters of carsare optimized.
