The ride comfort of the wheel loader is one of the important indicators to evaluate the quality of construction machinery. To evaluate the wheel loader ride comfort, a half-vehicle dynamic model is established to analyze and evaluate the effects of design parameters on the wheel loader ride comfort. The design parameters of cab’s isolation system such as stifness and damping coefficients are respectively analyzed based on two objective functions according to the international standard ISO 2631-1. The obtaine results indicate that the effects of the stiffness and damping parameters of cab’s isolation system on vehicle ride comfort are obvious. In addition, the results of the study are the theoretical basis for optimizing the design parameters of cab’s isolation system to improve the wheel loader ride comfort.
