Abstract

Hardware-in-the-Loop test facilities become a modern tool for testing of active systems in the automotive industry. Since real-time models are necessary for the vehicle dynamic simulation in HiL various techniques have been developed in the recent years to fasten the time integration of multibody system models. Nowadays a number of simulations is well established that help to avoid the time consuming simulation of the suspensions with kinematic closed loops. The so-called virtual axle is one of these approaches. It is based on tabulated kinematics of a wheel carrier that is evaluated during time integration. The virtual axle can be optionally extended with simplified wheel carrier elastokinematics as well. This paper presents the implementation of the virtual axle method in the multibody simulation package SIMPACK. Furthermore the accuracy of a vehicle model with the virtual axle is compared with a classical model including full suspensions with kinematic closed loops.
