Development of a CAE Technique for Vehicle Suspension Design -Roll Stabilizer Bar Modelling and Damper Design-

자동차 서스팬션의 설계를 위한 CAE 기법 개발 -롤안정바 모델링 및 댐퍼 설계-

In this paper. the Joint reaction forces in the suspension system of a passenger car are determined to calculate the deflections and stresses in the damper strut. A mathematical model of the Roll Stabilizer Bar(RSB) is developed to include the RSB forces in the dynamics analysis. Using these RSB forces, the variations of the damper forces and spring forces due to the wheel strokes are determined in a McPherson strut suspension. The graphs of shear force diagram, bending moment diagram, bending stress and deflections are drawn by the calculated joint reaction forces.
