Door Slam

The slam of a truck door is a dynamic process which influences the durability of the door structure. In this simulation example the flexible door was accelerated to reach a defined impact speed. A correct modelling of the sealing stiffness and the latch mechanism is necessary to reproduce the peak loading.

The analysis of the linear model without contact interfaces indicated unrealistic penetration of the stiffeners in the hinge area. By simulating the door slam with activated MAMBA contacts, a realistic loading could be reproduced. Both simulation results were utilized as input for a subsequent fatigue assessment. A comparison of the highest damaged locations emphasized the necessity of including contacts for a door slam simulation.
