摘　　要：座椅悬架对驾驶员乘坐舒适性具有重要影响。文章采用了滤波白噪声作为路面激励,综合路面仿真结果和车辆实际使用工况确定了仿真路面输入模型,对商用车进行了适当简化,通过Matlab/Simulink仿真,验证了安有座椅的"车辆—座椅—人体"三自由度模型与未安装座椅的"车辆—人体"模型相比具有较好的乘坐舒适性。The seat suspension has an important influence on the driver's ride comfort.The paper adopts filter white noise as the road surface excitation,synthesizes the road surface simulation results and determines the simulated road surface input model,and simplifies the commercial vehicle appropriately.Through Matlab/Simulink simulation,It is verified that the"vehicle-seat-human body"model with seat has better ride comfort than the"vehicle-human body"model without seat.
