This paper studies the factorｓ which affect the occupant injuries in Car-to-Car side impacts using CAE simulation .
The parameters of CAE simulation were derived from US-SINCAP(Side Impact New Car Assessment Program) test conditions and the field accident statistical data of NASS(National Automobile Sampling System).
The parameters varied in the CAE simulation were as follows:
And the comparing factors are Thorax injury severity (Thorax Trauma Index, TTI)and Pelvis injury severity (PELVIC G) as occupant protection of driver or passenger in the front seat position.
These studies make it possible to analyze directions for compatibility studies on side impacts including SUV (Sports Utility Vehicles), and these results are introduced herein. In addition, the occupant protection of a vehicle which obtained a result of TTI = 56G in the SINCAP test against a SUV was also analyzed and presented.
