Abstract :

Automotive vehicle performance has been a major focus of industrial research and development for nearly a century. While vehicle performance can be quantified in many ways like ride quality and handling is two aspects of performance directly related to suspension system. In a broader sense, vehicle’s ride quality is characterized by suspension with low spring rate, low damping rate, resulting in large suspension travel. On the other hand, for achieving good handling characteristics suspensions with high spring rates and high damping rates, resulting in small suspension deflections are incorporated. Suspension system basically consists of different components like spring, shock absorber and linkages that isolates excitations from road to wheels and then to vehicle. So, they perform a major role in obtaining desired ride and handling characteristics. Out of this, behaviour of shock absorber (damper) significantly affects the performance of suspension system. This is difficult to achieve unless and until parts of the whole system performs their assigned task satisfactorily.
