半挂式液罐车罐内液体晃动及其对整车侧翻稳定性影响研究现状

Research Status of Influence of Liquid Sloshing in Tank on Rollover Stability of Semi-loaded Tank Truck

半挂式液罐车具有载重大、运输效率高、经济成本低的特点,逐步成为我国液体货物道路运输的主力。车辆运行过程中罐内液体晃动和车辆运动之间的耦合作用大大降低车辆的行驶稳定性,使液罐车易发生横摆、侧翻等问题。文章主要对罐内液体晃动的常见研究方法及液体晃动对侧翻稳定性影响进行总结分析,为研究半挂式液罐车侧翻稳定性提供一定的理论基础。

With the characteristics of heavy load,high transportation efficiency and low economic cost,semi-trailer liquid tank truck has gradually become the main force of road transportation of liquid goods in China.The coupling effect between the liquid sloshing in the tank and the vehicle movement greatly reduces the driving stability of the vehicle,and makes the liquid tank vehicle prone to yaw,rollover and other problems.This paper mainly summarizes and analyzes the common research methods of liquid sloshing in the tank and the common control strategies to prevent the rollover of liquid tank truck,so as to provide a certain theoretical basis for the study of the rollover stability of semi-trailer liquid tank truck.
