Mastering Model Uncertainty by Transfer from Virtual to Real System

Abstract Two chassis components were developed at the Technische Universität Darmstadt that are used to isolate body and reduce wheel load fluctuation. The frequency responses of identified with a stochastic foot point excitation in hardware-in-the-loop (HiL) simulation environment hydropulser. modelling transmission behaviour influence testing machine on response was approximately represented time delay $$10\,\mathrm {ms}$$ 10ms range up $$25\,\mathrm {Hz}$$ xmlns:mml="http://www.w3.org/1998/Math/MathML">25Hz . This is considered by Padé approximation. It can be seen dynamics have an fluctuation acceleration, especially natural unsprung mass. Therefor, HiL stability analysed mapping poles system complex plane, influenced virtual damping. paper presents transfer from real quarter car quantify model uncertainty component, since impact does not occur test rig. base directly provided like case rig, compression spring damper calculated real-time simulation.
