Abstract: The project involves dynamic analysis of an automotive door beam subjected to impact by a ram, which is moving with a particular velocity. For the analysis of the side-door impact beam, the Finite Element Method (FEM) was used since it is the most widely used computational method in automotive design applications. A finite element basic model of the beam and the ram was developed in hypermesh 12.0. The objective is to run a FE analysis for this model and collect animation results, force-displacement plots, stresses etc. It was also required to collect plots at 6 inch of ram travel. It is also necessary to keep the stresses in the beam lesser than the ultimate stress of the material being used. Phase II is to simulate the door beam in complete vehicle with different design and different material composition.
The energy - time plots collected give us an idea about the amount of energy the beam could absorb under impact. Similarly the force displacement plots can give information about the load carrying capacity of the door beam. Two design improvements have been suggested for the door beam. These changes in the design have shown a good improvement in the load carrying capacity of the beam. For all these analyses it was observed that the stresses obtained at 6 inch ram travel were below the ultimate stress of the beam material and this prevents the beam from failing
