This paper describes the non-linear modelling of a double wishbone suspension developed to investigate the non-linear kinematics and dynamics in the closed, spatial kinematic chain configuration. Analytical and ADAMS models are generated and kinematic and dynamic characteristics of the models are investigated. The analytical model of the suspension mechanism is an idealized four degree-of-freedom (DOF) model, with suspension members considered as rigid links and bushings taken as linear spring—damper elements. The simulation results of the model subjected to a virtual kinematics and compliance (K&C) test are compared with results generated by an ADAMS model, developed based on parameters obtained from the vehicle manufacturer, subjected to the same virtual test. The experimental K&C testing on the test vehicle presents a method of capturing the kinematic characteristics of the suspension mechanism. The comparison of the simulation and experimental results presented shows that the models are capable of simulating the characteristics of the pre-existing suspension configuration of the test vehicle.
