Multi-link suspensions are the latest development in road car chassis design. They are conceived to provide high stiffness in the lateral direction and a reasonable compliance in the fore/aft (longitudinal) direction. This is due to the need of ensuring a good ride quality without affecting handling and safety. Ellis defines compliance as 'The change in suspension characteistics due to external forces'. The elastokinematic characteristics are usually tuned up to minimise camber and track changes and correctly tune toe variations. At the rear axle of a rear-drive car the central axis of elasticity can be positioned properly to result in a toe-in tendency under throttle-off condition, thus improving stability. The front axle of a front drive car can be designed with a 'virtual steering axis' to optimise the steering geometry. The paper presents the application of a simple algorithm for the force-displacement analysis of a five-rod suspension which allows the rubber bushing compliance.
