Use of concept modelling for online input force estimation

Cosco, F.I.; Naets, F.; Desmet, W.
ABSTRACT: Over the years, concept models have found increased use in the design of mechanical systems, such as automotive applications. However, these models can also be exploited as low-cost counterparts of high-fidelity models for use in online applications such as virtual sensors and control. In this work the use of structural models for input force estimation is discussed. Two different approaches are compared to model a twistbeam rear suspension for estimating the vertical input forces. the first model is an equivalent trailing arm description and the second is a modal reduced model. An experimental setup in which the forces are measured through a Kistler cell is used to estimate the vertical input force from an optical tracking system. The equivalent trailing arm model is shown to be incapable to produce accurate results due to the strong coupling of the vertical motion with the non-vertical loads, whereas the modal reduced model accurately reproduces the vertical forces.
