Three Wheeler - Occupant Simulation

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

1. Impact of TST (with occupants) with rigid barrier: Here the impact of the TST with a rigid wall has been studied when there is a passenger and a driver inside the TST.
   
   
2. TST (with occupant) travelling over a Bump: In this the TST with the occupants has been modelled when it goes over a speed breaker.
   
   

We have also studied various modifications like incorporation of seatbelts, paddings and changes in seating and have studied their effect in further improving the crashworhiness of these vehicles.

T = 0 ms	T = 20 ms	T = 40 ms
T = 60 ms	T = 80 ms	T = 100 ms
T = 120 ms	T = 140 ms	T = 160 ms
T = 180 ms	T = 200 ms	T = 220 ms
T = 240 ms	T = 260 ms	T = 280 ms
