摘　　要：为分析随机和脉冲路面对商用车行驶平顺性的影响,以某商用车为研究对象,依托多体动力学理论,使用ADAMS/Car软件构建包含前后悬架、轮胎、车身、转向系统及人体-座椅系统的车辆动力学模型,并对车辆进行了脉冲输入和随机输入平顺性分析,仿真结果表明:在脉冲路面的激励下,车速提高后车辆行驶平顺性提高;随机路面输入条件下,相较于B级路面,C级路面对平顺性的影响更显著,在商用车行驶舒适性评估和改进中应用更为有效。In order to analyze the influence of random and impulse road surface on the smoothness of commercial vehicles,a commercial vehicle is taken as the research object to construct the vehicle dynamics model containing front and rear suspension,tire,body,steering system and human body-seat system by using the ADAMS/Car software.The smoothness analysis of impulse and random input is carried out for the vehicle,and simulation results show that the smoothness of the vehicle increases after increasing the vehicle speed under the excitation of pulse road surface;the effect of smoothness is more significant on Class C road compared with Class B road under the random road surface input condition,which is more effective in the evaluation and improvement of driving comfort of commercial vehicles.
