摘要: 建立了偏载车辆的数学模型, 采用德国低干扰谱, 选择车辆直线运行速度为300km.h-1, 分析了偏载对车辆平稳性的影响趋势, 对比了纵向偏载和横向偏载对车辆平稳性的影响程度。分析结果表明: 随着偏载的增大, 车辆的整体平稳性逐渐变差, 纵向偏载将引起车辆前后端的平稳性产生较大的差距, 而横向偏载引起车辆前后端平稳性产生的差距较小, 因此, 为了提高车辆的整体平稳性, 应尽量减小车辆的偏载, 尤其应严格控制车辆的纵向偏载。Abstract: A mathematic model of partial load vehicle was set up. As an example of a high-speed vehicle running on tangent track with Germany low-disturbing spectrum at 300 km·h-1, the influences of all kinds of partial loads on the riding quality of vehicle were analyzed and compared by simulation. Analysis result shows that with the increase of partial load, the riding quality of vehicle is getting worse, longitudinal partial load has larger influence on the riding quality between the foreside and backside of vehicle, and lateral partial load has less influence on them. So in order to improve the riding quality of vehicle, partial load must be minished by all means, especially, longitudinal partial load must be strictly controlled.
