全挂汽车列车瞬态转向特性的分析研究

A Study on Transient Steering Behavior of A Truck-Trailer Combination,

由于全挂汽车列车的主车与挂车之间的相互作用,在转弯时,或在侧向力的作用下,常常导致主车、转向架和挂车三者之间产生剧烈的周期性摆动现象。为研究解决这一问题,将全挂车列车简化为主车、牵引架和挂车前轴、挂车车身和挂车后轴三个部分,并建立了运动方程式,研究分析了全挂车列车转向时车辆各参数的瞬态响应。

When a truck-trailer train is turning or under the action of lateral force, A serious cyclic swing often occurs among the towing vehicle, fifth wheel coupling and trailer owing to the interaction between towing vehicle and trailer. In order to study and solve this problem, the truck-trailer train has been simplified into three parts, i. e. towing vehicle, fifth wheel coupling plus front axle of trailer and cargo body plus rear axle of trailer, then the motion equations are accordingly derived, Finally the transient response of truck-trailer train with various parameters during turning is studied.
