摘　　要：本文采用一种新的更能合理地评价行驶车辆乘坐舒适性的评价方法作为目标函数的基础,对牵引车——半挂车的乘坐舒适性进行了优化分析。在考虑垂直、纵摇、横摇三向运动基础上,建立了包括座椅及驾驶室悬架运动的15自由度线性模型。经比较,既有座椅又有驾驶室悬架的优化情况的乘坐舒适性最好。This paper deas with optimigation and analysis of ride comfort for tractor and se-mitrailer using a new ride comfort criterion which can evaluate ride comfort of mov-ing vehicle more reasonably as the basis of objective function. Considering bounce,pitchand roll motions, the author established a linear model of 15 DOF that includedmotions of seat and cab suspensions. In comparison, the optimiged case with both se-atand cab suspensions has the best quality of ride comfort.
