Abstract
The vibration on the riding comfort of automobile vehicle is simulated. Main parts of the vibration on the riding comfort are modeled, and are analyzed. In the suspension modeling, the effect of the friction is studied, and In the engine mounting modeling, the effect of the position is studied. In the car body modeling, modal analysis in FEM is used. The simulation analysis is carried out using the passenger car model. In addition, the vibration reduction method is examined by the parametric study.
