原木汽车列车横向稳定性的分析

ANALYSIS OF TRAVERSE STABILITY OF LOG-TRUCK-TRAIN

对于拖带两节挂车的原木汽车列车的横向稳定性，应用力学Ｌａｇｒａｎｇｅ原理进行了分析，建立了列车的四个自由度横向振动作用力方程，并根据测得的数据，解其方程。该解对于研究列车行驶的横向稳定性。

The authors have used the Lagrange mechanics principle for analysing the traverse stability of log-truck-train,and established the four freedom of motion traverse vibration equation,and derived the equation according to the measure ddate.This method has important significance for researching the traverse stabitity of the log-truck-train and determining the structure type and size of the trailer.
