摘要
用多体方法建立三轴载货汽车整车动力学模型,用专门开发的数字化汽车道路仿真系统获得道路激励时域模型,同时建立对车辆振动响应量值进行客观评价的物理标量和对其主观评价的感觉模型。然后,对分立的不同主体模型进行组集,获得包含人、车、路交互大系统模型,为系统级研究车辆平顺性奠定了分析基础。
The fullvehicle dynamics modelhas been established by using the multi-body system method,a digital road been realized by a specific simulation software system, and both the objective and subjective response evaluation models been given by a filtration method. Then an integrated, enlarged model, taking the interaction of vehicle with road and rider into account, was achieved available to the analysis ofheavy vehicle vibration.
