The Dynamic Dent Resistance Analysis of Automotive Hood Outer Panel

Abstract:

Dent resistance of automobile panels becomes an important issue and quality criterion. In this paper, the dynamic dent resistance of automotive hood outer panel is analyzed by means of finite element method. The geometric model of automotive hood outer panel is firstly established by UG software. Then the finite element model of automotive hood outer panel is established in ANSYS. The dynamic dent resistance of automotive hood outer panel is analyzed by simulating the collision between a rigid ball and an automotive hood outer panel. The results show that compared with the traditional steel panel, the automotive hood outer panel made of aluminum alloy can reduce its weight by 36.3% while meeting the requirement of dynamic dent resistance. It is concluded that making automotive hood outer panel by aluminum alloy is feasible for automobile lightweight.
