Modeling, Analysis and Optimization in Vehicle System Dynamics

Abstract

Performance, safety, and comfort of a vehicle are related to its low-frequency motions. The corresponding mechanical models are characterized for all kinds of vehicles by stiff parts represented as rigid bodies and soft components like springs, dampers, and actuators (Figure 2.1). The method of multi-body systems is most appropriate for the analysis of vehicle motions and vibrations up to 50 Hz. In this contribution, the derivation of the equations of motions of multi-body systems is shown step by step up to the computer-aided evaluation of these equations. Figure 2.1 Multi-body models of vehicles: (a) road vehicle, (b) rail vehicle, and (c) magnetically levitated vehicle. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429129810/1b8617b2-a0d6-4758-a64d-91bb84aadcb7/content/fig2_1.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/>
