SIMULATION OF OCCUPANT KINEMATICS IN LOW SPEED REAR-ENDED VEHICLE COLLISION

Individual Project Requirements:

 

To simulate occupant dynamics in a car during the collision.

 

Procedure:

 

First the occupant's free body diagram was drawn:

 

The intial force F was calculated using a restitution coefficient of C=0.2. Research was done to find out human's body characteristics:

Next, the tranform functions were derived for each body part - torso, neck and head.

 

Calculated angular accelerations of each occupant's body part, right after collision at v=4m/s are shown below:

Simulation of the passeneger right after collision at v=4m/s:
