The joint forces and moments of a multi-link suspension are important parameters for fatigue analysis and experiment of bushings and control arms in the suspension. A modelling and calculation method for obtaining the joint forces and moments for a multi-link suspension is developed. In modelling of a multi-link suspension, a bushing is modelled with three translational stiffness and three torsional stiffness along and around three orthogonal axes. The force vs. displacement along one axis is non-linear and simplified as piecewise linear. Taking a rear five-rod suspension as one example, the forces and moments for each joint are calculated with the proposed method and compared with that using a conventional method. It is shown that the proposed model and calculation method can be used to evaluate the joint forces and moments for determining input loads for the design and fatigue test of bushings and control arms in a multi-link suspension.
