摘要

文章通过将解析法和多体动力学仿真法相结合的方法对考虑液体晃动的汽车罐车临界侧翻侧向加速度的计算方法进行研究,并提供了两种求解方法,分别为解析法和侧倾仿真法.通过假定汽车罐车侧向加速度恒定来将液体晃动简化为二维液体晃动,并通过液体重心位置的变化来等效液体晃动对汽车罐车侧翻的影响,获得了液体晃动、轮胎和悬架系统以及重心位置对汽车罐车侧翻的影响数据.该研究结果可为汽车罐车侧翻安全预警和事故还原提供参考依据.

Abstract

The purpose of this paper is to provide reference for safety warning and accident recovery of tank truck rollover.The calculation method of critical lateral acceleration of tank truck considering liquid sloshing is studied by combining analytical method and multi-body dynamics simulation method.In this paper,two methods are presented to solve the critical lateral ac-celeration of tank truck rollover considering liquid sloshing,which are analytical method and tilt table simulation method re-spectively.The liquid sloshing is simplified to two-dimensional liquid sloshing by assuming that the lateral acceleration of the tank truck is constant.The change of liquid center of gravity is used to be equivalent to the effect of liquid sloshing on tank truck rollover.The influence data of liquid sloshing,tire,suspension system and tank truck center of gravity on the rollover of tank truck are obtained.The research results can be applied to the safety warning and accident recovery of tank truck.
