[차량운동성능부문] 5링크식 멀티링크 현가장치의 설계와 실험차량에의 적용

Multi-link, suspension consists of five links which connect wheel and chassis with spherical joints or bushings. In kinematic point of view, multi-link suspension is considered as five spherical-spherical joints, i.e. five disptance constraints, and makes wheel to have one kinematic degree-of-freedom. This suspension has many advantages in kinematic design stage because it has many design variables and optimized design can be achieved to meet designer's needs. We developed conventional five-link type multi-link rear suspension with two design stages. First stage is the kinematic geometry design stage. In this stage, this new suspension must meet some kinematic constraints, such as toe change, camber change and roll center height change. Second stage is the compliance design stage. In this stage, bushings are selected by optimization technique. This mu1ti-link suspension is adapted to modular experimental vehicle, and validated by road test
