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
