The Study And Design Of Vehicle Energy-Absorbing Airbag Bumper

Safety, environment protection and energy conservation are the three principal problems of the automobile design and development in21st century. With the automobile possession rising, the traffic accidents are also increasing. Therefore, in present society, automobile collision safety issues are getting more and more attention. In the process of vehicle collisions, the front collision is the highest concurrent probability, this mainly involves the front bumper collision, however, car bumper on the market are mainly non-energy absorption in China, so the design and study of automobile energy-absorbing airbag bumper are very important to the collision safety.This paper introduced the main types of car energy-absorbing bumper and the form of its structure, proposed the innovative design concept of the energy-absorbing airbag bumper according to the energy-absorbing bumper developing and application, and explored the advanced nature of the energy-absorbing airbag bumper structure and technology. The design parameters of energy-absorbing airbag bumper were given, according to the characteristics and low-speed collision design regulations of the car bumper, and checked the strength and stiffness of the bumper system components, verified the rationality of its measurement parameters.Using the ANSYS13.0software, this paper analyzed the deformation of energy-absorbing airbag bumper analogous low-speed collision simulation. And carrying on the collision testing to the bumper under the identical collision conditions, recorded the deformation. The design structure rationality of the energy-absorbing airbag bumper is verified comparing and analyzing the simulation results with the experimental results.
