Background Information

Door frame of the car, set with the hinge mounts, and connected to the tubes on the chassis using the welded hinge pins

Requirements

Needs to withstand 5g loading as per ASC Regulations

Loading and Boundary Conditions

In order to simulate a load a bumper was added to the assembly. The bumper is 10cm high as specified by regulation, and was placed at the average height of a bumper for a large vehicle. Then the boundaries of the chassis tubes were fixed in order to fully constrain the assembly, and an acceleration of 49m/s^2 was applied to all bodies to simulate the 5 g load

The chassis and door frame have a no separation contact

The hinge pins have a bonded connection to the chassis tubes

The bumper has a bonded connection to the door frame

Results

von Mises Stress
Displacement
Mesh Independence	The geometry of the door frame was not conducive to mesh refinment, due to the trims of the tubes themselves. Because of this convergence could not be plotted. As a result a dense mesh refinment was added to the door frame and the bumper, to over refine the part initially, to prevent innacuracies in the simulation.
