In the vehicle suspension design, the optimal suspension should fulfill the following basic requirements: the ride comfort, reduction of dynamic road-tyre forces, and reduction of relative motions between the vehicle bodies. Controllable suspension systems are required to improve the compromise between the conflicting demands. Suspension system is the combination of various types of spring which include leaf springs, coil springs, air springs, rubber springs, torsion bar springs and shock absorber. They may be paired off in various combinations and attached by several different mounting techniques. Therefore, to check the comfort ability of a vehicle, it is necessary to find the deflections, stresses and stiffness or spring rates. Chrome Vanadium Steel ASTM-A231(Cold Drawn)material is chosen to analyze for rear coil spring. Working frequencies of rear coil spring are 1.3324 Hz and 8.3027 Hz respectively. Working frequencies do not match with natural frequency of rear coil spring at six mode shapes. Therefore, the designed coil spring is safe.
