Conceptual Design of a 3 Wheeler Motorbike – Stone Impact Simulation

The stone-impact resistance of the three wheeler bike fairing is studied here using the computational approach. Explicit finite element analyses are used for such high speed dynamic events and we use Altair RADIOSS which is a leading structural analysis solver for highly non-linear problems under dynamic loadings. The purpose of this study is to establish the modeling procedures for a stone impact case, and this approach can be used in future studies to predict damage evolution patterns for different fairing designs in automotive applications.

We are primarily interested in damage occurring in the fairing and so we model the stone as a rigid body and thereby we also test for the worst case condition that can happen in a stone impact.

As a continuation students can change the thickness of the fairing, increase the stone velocity, change the stone position…etc and thereby can observe the change in damage evolution patterns happening in the fairing.
