Abstract
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 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. Mathematically, this can be formulated as an optimal control problem. We present a strategy to solve this problem and an application to an off-road driving simulation of a Porsche Cayenne model.
