## Invariant input loads for full vehicle multibody system simulation

• Input loads are essential for the numerical simulation of vehicle multibody system (MBS)- models. Such load data is called invariant, if it is independent of the specific system under consideration. A digital road profile, e.g., can be used to excite MBS models of different vehicle variants. However, quantities efficiently obtained by measurement such as wheel forces are typically not invariant in this sense. This leads to the general task to derive invariant loads on the basis of measurable, but system-dependent quantities. We present an approach to derive input data for full-vehicle simulation that can be used to simulate different variants of a vehicle MBS model. An important ingredient of this input data is a virtual road profile computed by optimal control methods.
