Abstract

In order to evaluate a wheel loader ride comfort using hydraulic isolation system (HIS) of cab with the orifice and the annular orifice, a half-vehicle dynamic model of a wheel loader is established under different driving conditions. Time domain and frequency domain acceleration responses of the vertical driver’s seat and cab pitching angle are selected as the objective functions to analyze and evaluate vehicle ride comfort. The study results show that the amplitude values of the PSD acceleration responses of the vertical driver’s seat with 1.5c₀ value of HIS respectively reduce in comparison with 0.5c₀ value of HIS at the low frequency region from 2.0 Hz to 20 Hz. Finally, the different operating conditions are investigated and evaluated their effects on vehicle ride comfort with HIS, and the evaluation results indicate that the values of the root mean square (RMS) acceleration responses of the vertical driver’s seat (a_ws) and cab pitching angle (a_wphi) change greatly when operating conditions get worse, which means that operating conditions greatly affect vehicle ride comfort.
