From LMS International

LMS International, working in conjunction with BMW, FH Aachen and MAKROSS, has developed an analytical process that allows predicting the durability performance of vehicle doors. The scope of this project comprises the use of virtual simulation to predict the ability of components to withstand door slams. It combines explicit Finite-Element (FE) analyses using modal superposition techniques, and durability simulations to convert the obtained local stress histories into fatigue-life predictions. When further elaborated and optimized, this approach has the capacity to provide reliable insights in the durability performance of body and door components, before physical prototypes become available. In the future, this way of working may potentially replace or complement BMW's current approach, which includes performing physical tests on vehicle prototypes.
