On The Analysis Of Double Wishbone Suspension

Abstract

This paper introduces novel approaches for analysis of the double wishbone suspension mechanism. In the literature, to the best of our knowledge there is no analysis study available for the double wishbone mechanism that is performed "analytically". Initially kinematic model of the double wishbone mechanism is established. Then, a kinematic analysis methodology is presented. This analysis procedure is carried out analytically. The essential parameters; camber, caster, kingpin, toe angles, and track variation are defined according to the kinematic model. A double wishbone suspension mechanism is synthesized as an example by using the method presented in this study. Variations of the essential parameters with respect to wheel travel are plotted. The synthesized mechanism is established both in Lotus Suspension Analysis and Catia software and same results with the analytical model are obtained. Thus, it is verified that mechanisms of different dimensions c an be analyzed and parameters can be optimized precisely and swiftly by using this analytical approach.
