MULTI-LINK STRUCTURE FOR REAR INDEPENDENT SUSPENSION OF HEAVY VEHICLE

Automobile systems today is going through major changes and as concert to comfort the suspension system and it’s working is very important. The study of four link suspension system and dynamic analysis are discussed in this paper. This paper discusses the design problem of vehicles using four-link suspension systems with the aim of totally optimizing vehicle handling and stability. Since this problem includes many evaluation items, and Four-link suspension system has interconnected behavior, the optimization is so complicated. An efficient and computable model is indispensable for compromising the total optimization. This paper investigates a structure of objectives, introduces appropriate simulation model s for respective items; we apply multi body dynamic analysis to plot the varies terms such as w heel travel, camber angle, caster angle, toe-in, toe-out etc. The result of optimization calculation shows the validity of the optimization model
