Abstract:

Oblique crash is one of the most common types of traffic accidents. However，there are only few researches and related regulations available on oblique crash and their protection object is mainly the 50^th dummy， without paying due attention to 5^th and 95^th dummies. In order to improve the relevant standards on vehicle safety and further reduce the casualties in oblique crash accidents， a test platform for 18° oblique crash is built， three test methods are established， and data of 69 tests for 15 vehicle models are compared to analyze the injuries of different parts of the 5th， 50th and 95th dummies. The results show that the neck， pelvis and right thigh of the 50th dummy have the highest risk of injury， the head and chest injury indicators of the 5th dummy are 12.2% and 34.1% higher than that of the 50th dummy respectively， while the left thigh force of the 95th dummy is 456.8% higher than that of the 50th dummy， indicating that all drivers with different statures shall suffer injury to different degrees in 18°oblique crash. This study provides the most powerful data and technical supports for further improvement of related vehicle safety standards and also has guiding significance for vehicle enterprises in optimizing vehicle design.

Key words: oblique crash, sled test, dummy injury, comparative study
