Ride Behaviour of Three-Wheel Vehicle using Semi-Active Suspension using Skyhook Control Strategy

Abstract

This paper analyses the ride behaviour of a 2 degrees of freedom model of three-wheel vehicle subjected to bounce and pitch velocity inputs. This paper also demonstrates the isolation properties of semi-active suspension using skyhook dampers. The results show semi-active suspension can provide isolation near resonance as compared with passive suspension when subjected to bounce and pitch velocity inputs. Below and beyond the resonating frequencies, the behaviour of passive and semi-active suspension is identical for all damping values.
