Abstract
The assembling of the IWM (IWM) leads to a sharp increase in unsprung mass. In order to study its impact on the handling and ride comfort of IWM vehicles, a three-motor four-wheel drive (4WD) vehicle is taken as the study object, and a multi-body dynamic simulation model is established by ADAMS for the analyzing of handing performance of the vehicle. Results show that the increase of unsprung mass has little effect on handling performance under national standard routine test conditions. Based on MATLAB/Simulink software, the vibration model of 1/4 vehicle is established, and the ride comfort is simulated and analyzed in frequency domain and time domain, and the influence trend of vehicle parameters on ride comfort is quantified. Through disturbance sensitivity analysis, the influence degree of vehicle parameters on ride comfort is quantified, and the general rules of IWM vehicles design and ride comfort tuning are summarized, which has guiding significance for design and performance tuning of IWM vehicles.
