This paper describes a very simple sled test method to simulate the thoracic behavior of dummy in the side impact test situation of SUV representative impacting a passenger car side. In this sled test, the door inner panel which was deformed in the full scale test was rigidly set on the sled, and impacted the dummy. Even if the sled moved in normal V-T profile used in HYGE sled facility, the dummy responses were correlated with full vehicle tests in order to study occupant protection practically. This test method could be applied for both SID2s and Eurosid dummies.

In addition to the real sled tests, FE simulation was also used to analyze the influences of various factors. In conclusion, it was found that the sled test with deformed door was a useful and efficient method to study for occupant protection. With this test method and FEM, it was found that one of the ways which has possibility to reduce injury index of SID2s is to disperse the impacting force by Side Airbag or door trim.
