摘　　要：为更好评价微型客车的行驶平顺性,根据微型客车实际布置的特点,基于一定假设建立了微型客车1/2汽车七自由度系统振动模型。推导出微型客车的车轮静载荷和各个振动响应量的表达式。应用最新国标GB/T 4970—2009,实现了路面脉冲输入下微型客车行驶平顺性的仿真。为路面随机输入下微型客车行驶平顺性的分析奠定了模型基础。To evaluate ride comfort of minibus, the plane vibration model of minibus with seven degree-of-free- dom is established according to the real arrangement of the minibus and the some assumptions. The expressions of two wheel static loads and the vibration response variables are derived. Ride comfort simulation of minibus under road pulse input is carried out based on Chinese standard with number of GB/T 4970 - 2009. The research lays the model foundation for ride comfort analysis of minibus under road random input.
