Abstract

Suspension system is the combination of various types of spring which include leaf spring,coil spring, air spring, rubber springs, torsion bar springs and shock absorber. In this research, rear coil spring design of Landcruiser Pardo is taken as existing design. The model of vehicle is Toyota Landcruiser Pardo(KD-KZ195W).This model holds the engine model 1KZ-TE with four cylinders which displacement is 2982cc. The overall length, width and height of vehicle are 4675mm, 1820mm and 1880mm. The design of existing coil spring is made of Stainless Steel. In this research different materials were analyzed. From the analysis, Chrome Vanadium Steel is suitable material which holds optimized functions and properties rather than two other materials. As a result of this research, the optimized coil spring has the spring index of 7.849, spring rate of 67.56N/m, free length of 244.56mm and pitch of the spring wire as 0.04m. The maximum shear stress of optimized design with the value of 614MPa which is less than the existing design.
