Simulation of Vehicle Pitch in Sled Testing

In HYGE sled simulations of 35 mph barrier crashes with the Volvo 760 dummy kinematics and injury criteria have been different from what can be observed in barrier crashes

One of the major differences between sled testing and barrier crashes is the car pitch in the barrier crashes.

In order to improve the sled testing a method to simulate pitch on the sled was developed.

Dummy kinematics and injury criteria from sled tests with pitch simulation have proved to be in good agreement with results from barrier crashes.

The paper will give a more detailed description of vehicle pitch, the sled pitch arrangement and a comparison of dummy kinematics and injury criteria from barrier crashes and sled testing with and without pitch displacement.
