摘　　要：地铁车辆上的很多部件在运行时都有相对位移,这使得在设计阶段无法直观地模拟出各个部件之间的干涉情况。因此,在尽量保证其较高安全系数的基础上,往往需要进行较大空间的放量。在无法提供较大间隙的地方,设计难度会大大增加,通常需要反复进行校核,将各方向上的运动情况都考虑到位,虽然对某个部件的耗时不多,但整车上部件很多,对每个部件都进行校核会浪费很多的设计生产时间,故在装车前能快速简便地确认各部件的运动限界情况,进行针对性地改进设计,是当下急需解决的问题。文章提出了校核悬挂件运动限界的3种方法,即三维模拟、二维模拟和工装辅助直观模拟,均可预先展示实际运动的外轮廓情况,一旦出现干涉可更换方案予以解决,能降低摩擦磨损和碰撞冲击等带来的部件损坏甚至功能缺失,最大程度地保证了产品使用寿命及行车安全。Many metro components have relative displacement during operation,which makes it impossible to simulate the interference between various components in the design stage.It is often necessary to reserve a large space to ensure its high safety factor as much as possible.Where a large space can not be provided,the design difficulty will be greatly increased,and it is usually necessary to check repeatedly and take all directional movements into account.Although it does not take much time for a certain component,there are many components on the whole vehicle,and checking each component will waste a lot of design and production time.Therefore,it is an urgent to quickly and simply confirm the motion limits of each component before loading and improve the design.This paper puts forward three methods to check the motion limit of suspension parts,namely,three-dimensional simulation,two-dimensional simulation and tooling-assisted intuitive simulation,all of which can show the outer contour of actual motion in advance,and once interference occurs,it can be solved by alternative schemes,which can reduce the damage of components and even the loss of function caused by friction and wear,collision impact,etc.,and ensure the service life and driving safety of products to the greatest extent.
