타이어특성을 포함한 단순차량모델의 동특성

The dynamic stability of a vehicle is a very important subject in vehicle design and control, because vehicle safety is closely dependent upon its dynamic stability. This study is devoted to make nonlinear vehicle models for stability analysis and simulation of the dynamic behaviors of a vehicle. Consideration to the degree-of-freedom and the linearity results in two types of vehicle model. The simple model is for seeking the stability region, the complex one, a multi-body dynamic model in MSC.ADAMS, is for accurate simulations. The major data of a mid-size passenger car are used, and some test results are compared for the model validation.
