摘　　要：以分别基于双叉臂式和麦弗逊式独立悬架为前悬架的某两轿车为研究对象,运用机械系统动力学仿真软件ADAMS/Car ride模块建立了包括前后悬架、轮胎、车身和转向系等子系统在内的整车仿真模型;基于Sayers数字模型生成B级随机输入路面,按照国家标准进行随机输入路面汽车平顺性仿真。通过计算随机输入下汽车总加权加速度均方根值,对两轿车的平顺性进行对比评价。结果表明:B级随机输入路面下前后悬架均为双叉臂式的轿车具有较好的平顺性,对轿车悬架系统的开发和轿车乘坐舒适性的改进设计提供了理论依据。A certain two cars respectively with double wishbone suspension and Mac Pherson independent suspension as front suspension are used as the research object. The vehicle simulation models including front and rear suspensions,tires,body,steering system and other subsystems were built up by the mechanical system dynamics simulation software ADAMS / Car ride module. Random input B-class road is generated through Sayers digital model,and random input road car ride comfort simulation is carried out according to the national standards. The comparative evaluation of two cars＇ ride comfort is realized by calculating the total weighted acceleration root mean square value. The results show that the car with double-wishbone suspension as front and rear suspension has better ride comfort under Bclass random input road,and it provides the theoretical basis for the development of car suspension system and vehicle ride comfort improvement design.
