本文概述了挂车横向摆动及其严重后果和挂车横向摆动的研究情况。作者进行了挂车横向摆动的下述理论分析:1.轮胎侧向偏出系数和车轮侧向偏出角;2.轮转向挂车的运动方程;3.轴转向挂车的运动方程;4.方程求解和摆动曲线;5.临界车速的确定;6.若干结构因素对稳定性的影响。并做了挂车摆动的机械模拟试验。在理论分析和模拟试验中都没有考虑悬架的因素,以及加速、制动的影响。而这些都与挂车稳定性有关系。此文仅仅是初步的探讨。致于带弹性悬架的挂车的稳定性,以及制动时汽车列车的方向稳定性有待探讨。
This paper summarizes the research on the lateral swinging of trailers and their serious consequences and the lateral swing of the trailer. The following theoretical analysis of the transverse swinging of the trailer is carried out by the author: 1. Lateral deflection coefficient of the tire and lateral deflection angle of the wheel; 2. The equation of motion of the wheel steering trailer; 3. The equation of motion of the axle steering trailer; 4. The solution of the equation And the swing curve; 5. Determination of the critical speed; 6. Several structural factors on the stability of the impact. And made the trailer swing mechanical simulation test. In the theoretical analysis and simulation tests are not considered the suspension factors, as well as acceleration and braking effects. And these are related to the stability of the trailer. This article is only a preliminary discussion. The stability of the trailer with elastic suspension and the direction stability of the train when braking are to be discussed.
