首次利用坐标变换的方式建立了车辆悬架系统模型,把工程中常用的加速度信号作为模型的输入,不仅提高了模型的计算精度,而且更加具有实用性。选取典型路面,通过实际测量的方式获取前、后桥的加速度信号,对多个方案进行优化仿真,得到了合理的悬架匹配方案。相关的模型及研究方法为悬架系统的合理设计提供了理论依据,为今后车辆进一步仿真研究提供了参考。
For the first time, the model of vehicle suspension system is established by means of coordinate transformation, and the acceleration signals commonly used in engineering are taken as the input of the model, which not only improves the calculation accuracy of the model, but also is more practical. Select the typical pavement, obtain the acceleration signals of the front and rear axles through actual measurement, optimize and simulate a number of schemes, and get a reasonable suspension matching scheme. The related models and research methods provide theoretical basis for the reasonable design of the suspension system and provide reference for further vehicle simulation in the future.
