고강성 차체 구조 연구

The Stiffiness of Body B.I,W is the important factor of a vehicle performance. For high stiffness, analyze the body structure using HSA method. And find the high influence position of stiffness for sensitivity analysis. According to the result of sensibility analysis, we developed high stiffness body tough improved joint structure and structure foam(CBS). This paper describes the relation of high stiffness body for ride and handling performance through the real vehicle test applied improvements structure. These proposed body structure can be provide the guideline for development better vehicles.
