Structural Design and Optimization of Plate Form Trailer in EDR Low Speed Crash Test

Abstract

Although the number of traffic accidents in our country has decreased year by year in recent 10 years, it is still one of the countries with high incidence of traffic accidents in the world. EDR (Event Data Recorder) can obtain the parameters which can not be obtained by the traditional accident investigation, and it becomes an important supplementary content of the traffic accident database.. According to the requirements of EDR low-speed crash test, this paper designed a plate form trailer for test. Through processing and test verification, the structural optimization of the plate form trailer body, steering mechanism and test vehicle fixed device is carried out. After structural optimization, the compatibility, flexibility and impact resistance of the plate form trailer are significantly improved, which is of great significance to the research of EDR testing technology and industrial development.
