Abstract:

In order to evaluate the impact of off-road terrains on the ride comfort of construction vehicles, a nonlinear dynamic model of the construction vehicles interacting with the terrain deformations is established based on Matlab/Simulink software. The weighted root mean square(RMS)acceleration responses and the power spectral density(PSD)acceleration responses of the driver’s seat heave, the pitch and roll angle of the cab in the low-frequency region are chosen as objective functions under different operation conditions of the vehicle. The results show that the impact of off-road terrains on the driver’s ride comfort and health is clear under various conditions of deformable terrains and range of vehicle velocities. In particular, the driver’s ride comfort is greatly affected by a soil terrain while the comfortable shake of the driver is strongly affected by a sand terrain. In addition, when the vehicle travels on a poor soil terrain in the frequency range below 4 Hz, more resonance peaks of acceleration PSD responses occurred than that on a rigid road of ISO 2631-1 level C. Thus, the driver’s health is significantly affected by the deformable terrain in a low-frequency range.
