Download Dissertation Abstract The statistics from around the world show that the number of deaths is constantly increasing every year, because of road traffic accidents, so car accidents become one of the major social problems that endanger the safety of human life.

And in the process of vehicle collisions, the highest probability of occurrence is the front, the first relates to the front bumper of the collision.

In the case of car crash, bumpers have their indispensable "roles in impact energy absorption, car body protection, passenger and pedestrian injury alleviation and prevention. Therefore improving bumper crashworthiness and energy absorption characteristics is very realistic and important for improving vehicle crash safety.

INNOVATING FOR 40+ YEARS

On the base of systematic summarization on the critical problems, research methodologies and research situation of bumper low speed impact, according to CFVSSbumper low-speed collision regulations, firstly, some car model is established in this paper using CATIA software.

The geometric model of meshing, the definition of material properties as well as component connection is done by using Hypermesh software. And choosing LS-DYNA software, boundary conditions and the control conditions are set for the vehicle collision model.

Via analysis of deformation, velocity and acceleration of the bumper proposes advice on crashworthiness of the bumper beams. Using of the simulation results analyze rationality of the new bumper from the aspects of deformation and equivalent stress-equivalent plastic strain.

And then, comparing the new bumper with the original on energy analysis we obtain better crashworthiness of the new bumper structure.

So that shows the reliability of the new bumper.Press forming of paperboard is studied with aid of finite element simulations. • Especially the effect of creases on the formability is studied.

In mathematics, a finite set is a set that has a finite number of srmvision.comally, a finite set is a set which one could in principle count and finish counting. For example, {,,,,}is a finite set with five elements. Preservation of Knowedge, peak oil, ecology - Cars, light trucks, and buses are irrelevant to preventing collapse.
