摘　　要：通过对长管拖车气瓶道路运行实际问题的认识和分析,建立了长管拖车气瓶的有限元分析模型,采用弹塑性分析方法,对不同工况下的运行工况进行研究,得出了向心加速度对长管拖车气瓶的影响较大。为了进一步研究向心加速度对长管拖车气瓶的影响,再次研究了长管拖车在匀速圆周行驶时向心圆周速度为0.5-4.0rad/s的位移应力和疲劳结果。研究表明:向心加速度能对气瓶的位移应力和疲劳产生比较大的影响,当向心圆周速度等于2.0rad/s时,气瓶的最大等效应力接近材料的屈服极限。对长管拖车气瓶道路运行研究,为长管拖车气瓶的设计制造检验提供了参考。Weconstracted the finite element analysis model of tube trailer gas cylinder according to actual situations.Taking elastoplastic analysis method,withreseasch of different running working conditions,it shows that the centripetal acceleration has greater influence on tube trailer gas cylinder.In order to research the influence on tube trailer gas cylinderfurther,the results of displacement,stress and fatigue were researched again under uniform circular motion with the centripetal circular velocity ranging from 0.5rad/s to 4.0rad/s.The research shows that when the centripetal circular velocity is 2.0rad/s,the maximum von Mises stress is closed to yield limit.The road running research of tube trailer gas cylinder can provide a reference for the design, manufacture and inspectionof tube trailer gas cylinder.
