The comfort level and ride stability of a vehicle are two of the most important factors in a vehicle's subjective evaluation. In the design of a conventional suspension system there is a trade off between the two quantities of ride comfort and vehicle stability. There are two basic types of elements in conventional suspension systems. These elements are springs and dampers. The role of the spring in a vehicle's suspension system is to support the static weight of the vehicle. The role of the damper is to dissipate vibrational energy and control the input from the road that is transmitted to the vehicle. This paper presents the simulation of vehicle ride model. This model may be used for vehicle suspension testing to carry out the ride analysis at different vehicle speeds. The quarter and the full vehicle model are created, using ADAMS (Automatic Dynamic Analysis of Mechanical Systems). The two models include all sources of compliance; stiffness and damping. The road excitation is causing sudden vertical movements between the bump and the rebound. Therefore, the suspension moves, the position and orientation is calculated. The main output from this analysis is the response in terms; displacement, velocity, and acceleration. These parameters are measure of stability and ride comfort at different vehicle speeds. This paper introduces the simulation of vehicle ride models via quarter (2-DOF) and full vehicle model (6-DOF)
