The Directional Response of Log Hauling Truck - Doglogger

A planar mathematical model for various design configurations of the doglogger truck, the tractor triaxle trailer combination and the tractor quadaxle trailer combination is developed. A kinematic and dynamic analysis of this vehicle model is then carried out and the governing equations for planar yaw motions are derived. Using the computer simulation model, dynamic responses of the vehicle are investigated through transient and harmonic response calculations, and a parametric sensitivity study is carried out.
