摘要:

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,以及确定运材挂车的结构形式和尺寸都有重要意义。

Abstract:

The authors have used the Lagrange mechanics principle for analysing the traverse sta bility 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.

Key words: Log-truck-train, Vibration system, Natural frequency
