双横臂悬架DMU运动校核模型搭建与校核方法分享

DMU Motion Check Model Construction and Output Sharing of Double Wishbone Suspension

双横臂悬架多用于高端的乘用车,可匹配阻尼可调减振器、空气弹簧等元件,使整车舒适性和操控性更好。随着技术进步,双横臂悬架在高端商用车领域逐渐普及,如高端轻卡、轻型客车等。双横臂悬架的上摆臂、下摆臂、减振器、转向拉杆等零件集中布置,对空间要求很高。为防止发生装配困难、运动干涉等,零件的运动空间校核显得尤为重要。本文介绍双横臂悬架DMU运动空间校核模型搭建,及运动校核结果输出方法,可供工程技术人员参考。

Double wishbone suspension is mostly used in high-end passenger vehicles,and can be matched with adjustable damping shock absorbers,air springs and other components to improve the comfort and handling of the whole vehicle.With technical progress,double wishbone suspension is gradually popularized in the field of high-end commercial vehicles,such as high-end light trucks,light buses,etc.The upper arm,lower arm,shock absorber,steering link and other parts of double wishbone suspension are arranged in a centralized manner,which requires high space.In order to prevent assembly difficulties and motion interference,the motion space check of parts is particularly important.This paper introduces the establishment of DMU motion space check model of double wishbone suspension and the output method of motion check results,which can be used as a reference for engineers and technicians.
