Research paper thumbnail of Using a quarter-vehicle multi-body model to estimate the service loads of a suspension arm for durability calculations

Proceedings of the Institution of Mechanical Engineers, Part K: Journal of Multi-body Dynamics, 2003

In practice, these loads can only be determined experimentally once a physical prototype exists. If durability is to influence the design process at an early stage, representative loading conditions must be evaluated virtually using tools such as the multi-body system (MBS) technique. This paper investigates the simulation of loading conditions for a suspension arm of a multipurpose vehicle using a quarter-vehicle model (QVM) of varying complexity. Like the physical durability test, the model is driven over a virtual pavé road, which subjects the virtual prototype to inputs likely to cause significant damage, thus placing exacting demands on the model. Though predicted resonant frequencies are close to those measured, comparison between experiment and simulation reveals discrepancies in the amplitudes of acceleration. Possible causes are investigated by studyi...

Very efficient stress analysis and fatigue life assessment techniques are needed if this is to become routine. For the first time, this paper compares several approaches to fatigue life prediction using a real automotive engineering case study, taking into account
