Abstract
This paper presents an experimental analysis of 2 degree-of-freedom quarter-car passive suspension system (2 DOF QC-PSS) and 2 degree-of-freedom Semi-active suspension system (2 DOF QC-S-ASS) (typically composed of a controlled damper and a passive spring) for ride comfort. A quartercar suspension system consists of the sprung mass, unsprung mass, a suspension spring and damper and a tire spring. A damper with Electro- Rheological (ER) fluid has been considered as one of the most feasible choice for a semi-active suspension system due to its Rheological properties and low cost. Thus this model is modified to a 2 DOF Quarter-car Semiactive Suspension System by placing ER Damper, with its assistant control instrumentation, in between sprung and unsprung masses. The results illustrate considerable improvement in ride comfort above the conventional passive system. The details of the quarter-car model progress with the test set-ups for the passive and hydraulic semi-active suspension systems, suspension elements employed, experimental analysis and results are presented.
