摘　　要：轿车改装燃料电池动力系统后,整车参数发生了变化,悬架也相应调整。文中在ADAMS/CAR中建立了某燃料电池轿车整车模型,通过驾驶员控制文件的定义对典型行驶工况进行仿真试验,根据国标对该车的操纵稳定性进行了综合评价。结果显示,由于整车参数变化及悬架的调整使得该车的不足转向特性偏弱,最后分析其原因并提出了改进措施。The saloon car after being refitted into a fuel cell dynamic system, variations happened on the parameters of the entire car and a corresponding adjustment was made as well on the suspension frame. The entire car model of certain fuel cell car was established in this paper by ADAMS/CAR. The simulative experiment was carried out on the typical traveling operative condition by means of the definition of driver control documents. A synthetical evaluation was carried out on the steering stability according to national standard. The result showed that as a result of the variation of the entire car parameters and the adjustment of the suspension frame caused the car a rather weak performance of insufficient turning, finally its reason was analyzed and an improving measure was put forward.
