For expanding virtual methods in vehicle dynamics development, precise and real-time capable suspension models are required. Especially the elastokinematic properties have to be represented very thoroughly. This contribution presents a model of an elastokinematic double wishbone front suspension with topology and parameters typical for passenger vehicles. It has a total of 144 degrees of freedom and a high numerical stiffness. To enable computationally efficient integration, a linear-implicit integration method is used. To achieve good scalability of computational effort and accuracy, the determination of the necessary Jacobians is separated from the actual integration, so that both can be performed with different step sizes. Dynamic suspension tests are used to show the influence of the step sizes on the accuracy of the method.
