The Simulative Value Analysis of the Effect of Vehicle Collision Speed on the Safety

According to the finite element principle, an analysis is made of the pitch point displacement, which the automobile collision distorts. The frontage collision distortion process is also analyzed with the distortion rigidity method. Through the analysis of the automobile speed, ranging from 48km/h to 56km/h and the rigid wall frontage collision of the simulative automobile body distortion result, it can be concluded that as the collision speed increases, the automobile's front body distortion enlarges, and the cab mean acceleration also increases along with the collision speed enhancement. When collision speed increases the self-protecting sector rigidity of the automobile body should be strengthened so that the crew member's safe can be guaranteed.
