STUDY ON PERFORMANCE OF SEMI ACTIVE VARIABLE DAMPING RIDE COMFORT SUSPENSION FOR AUTOMOBILES

Abstract

for comfort ride, handling, and safety of road vehicles suspension systems are of high importance.
Conventional passive type suspension systems do not offer ride comfort on uneven road surfaces, corners, long bumps
and short bumps. For a comfortable ride, all the conditions mentioned above require different damping ratios thereby to
overcome these conditions a variable damping system is needed. A magneto rheological system for control of damping is
introduced in the majority of high-end cars and recreational vehicles. The magneto rheological systems are effective but
these systems are extremely costly and hence for budgetary reasons it cannot be applied to small cars and vehicles. The
objective of this paper is to analyse the performance of a variable damping system at all above conditions of a ride by
application of hydraulic dampers with orifice control system that will enable to control the damping ratios. Prototype of
semi-active damper has been developed and experimentation was carried out. To analyse performance of system trial of
developed system was taken.
