The objective of this work is to understand the injury encountered by the occupant as well as by the pedestrian during these impacts. The three-wheeler chosen is Bajaj Three Wheeler. The occupants as well as pedestrian are modeled using the standard dummies developed by TNO, Netherlands, for these impacts. The experimental data for the force deflection properties of the different parts of three-wheeler have been obtained from Bajaj Auto Limited.

While some of these models have been developed in commercial simulation packages, in some studies we have also developed the vehicle dynamic equations and implemented their solution in MATLAB. Figure below shows the model of the Bajaj three-wheeler as developed in MADYMO.

We have developed a number of types of simulations for the TST:

1. 3 Wheeler - Occupant Simulation

2. 3 Wheeler - Pedestrian Simulation

3. 3 Wheeler - Rollover Propensity
