Simply stated, we need a suspension in vehicles, to ensure that the we get a smooth ride and to allow the vehicle to be handled properly.
A supermarket trolley does rattle a lot when we take it to the parking lot on a surface rougher than the store flooring. The vibrations received from the ground are directly transmitted to the basket of the trolley as the wheels are mounted on the basket structure without any suspension.
A vehicle without a suspension would find itself in a similar situation. Riding in such a vehicle would be very uncomfortable.
Engineers while designing a vehicle's suspension focus on making the ride and handling of the vehicle as comfortable as possible. They do this for a variety of ground surfaces and for a range of vehicle speeds.
So suspension design aims to do two main things:
First is to insulate the occupants of the vehicle from shocks and vibrations transmitted from the ground to the wheels.
Second to ensure that the wheels of the vehicle stay in contact with the ground and to enable the control and steering of the vehicle.
These two aims are achieved by having springs and dampers, these being the dynamic elements of suspension, and linkages from the vehicle body to the wheels, which are the kinematic elements of suspension.
The way in which we design and construct the dynamic and kinematic element of suspension shape the ride and handling characteristics of vehicles.
