A Comparison of Different Forms of Small Overlap Tests

Small overlap crash covers 48% of all road accidents every year and is being a most common form of accidents. Analysis of different test methods of NHTSA RMDB offset oblique, IIHS small overlap and car-car 25% small overlap is made. A mid-level sedan is chosen for the test of three kinds of offset impact. Through the comparative analysis of car body deformation, body motion state and dummy injury, differences among these tests are figured out. The causes of the differences are put forward: impact velocity, overlap rate and barrier material, etc. In this way, a reference guide is given for the improvement of car crash safety.
