某6101型客车车身骨架结构动态扭转响应分析

摘要

Taking a 6101 type bus body frame as the research object, using ANSYS software, the finite element model of the body frame structure is established. Dangerous condition obstacle is simulated by the right front passenger train over the pavement sine wave mode,the transient response analysis of bus dynam-ic twisting process,the displacement of dangerous points of the body and the stress time history. The results show that the maximum stress of a 6101 type bus in 0.045 seconds can reach 130MPa, which provides a theoretical basis for improving the structure of the body.%以某6101型客车车身骨架为研究对象,应用ANSYS软件,建立了其车身骨架结构有限元模型.采用客车驶过正弦波形路面的方式模拟右前轮越障的危险工况,分析了客车动态扭转过程中瞬态响应,得到了车身危险点的位移和应力的时间历程响应.结果表明:在动态扭转工况下,某6101型客车在0.045秒时最大应力达到130MPa,为改进车身结构提供了理论依据.
