ANALYSIS OF TRANSIENT VIBRATIONS OF A TRUCK UNDERCARRIAGE DUE TO ROAD UNEVENNESSES

Abstract

In the bar-model dynamic analysis of truck undercarriage frames of open-section bars, dynamic equilibrium equations in terms of either centroid or shear centre coordinates of the bar cross section are equally useful. Results obtained in the computer analysis of transient vibrations of a truck undercar- riage by the two different equilibrium equations have been compared. Also simulation of wheel bouncing while crossing a road defect has been concerned with.
