There is a different purpose of a vehicle which has different types of suspension systems. This is the most popular suspension system. Today, these packages model almost every conceivable suspension system. Many different types of tires exist, but every tire relies upon its contact patch with the road (Shown in diagram T1 below) to create the friction needed. In a running vehicle, it is the suspension system that keeps the occupants comfortable and isolated from road noise, bumps, and vibrations. Airbags and seatbelts are safety features we often think of first, but the suspension system is an unsung hero in this arena. Determination of design parameters for cabin suspension system.
