摘要
在系统分析大客车结构和载荷分布的基础上,根据乘员人体工效学和系统动力学原理,建立起了考虑乘员人体和纵向制动力的大客车14自由度操纵动力学模型。同时还给出了应用该模型对大客车高速制动操纵稳定性进行仿真的一些结果,验证了该模型的可行性和实用性。通过对比分析得出,横向稳定性的安装位置较大地影响客车的操纵稳定性能。
A dynamic model of fourteen-degree of freedoms which involves the braking force in the coach is built up according to ergonomics and system dynamics, based on the analysis of the stucture and load in the coach and the relative roll movement of passengers. Simulation results are presented. The model is proved to be practical. Some influential factors such as the position of lateral stable pole are also discussed, which provide the basis for the designing and safe running of coach.
