A CAE simulation for the slam durability test of moving parts is proposed using explicit code. Previously other techniqes usging implicit code were proposed, but they are restricted in the description of the impact of the moving parts. To overcome the restrictions, Explicit code is adopted and proper modeling methods are proposed for the moving parts which includes side doors, hood, trunk lid. In this paper, the detail modelings of subcomponents are proposed including weather strip, locking mechanism, latch, striker, gas lifter, balance bar. Using the developed modeling technique, slam simulations and stress analyses are done and the life is predicted for the door, hood and trunk lid. Also the future works is discussed to simulate the behavior of the moving parts better with the test result.
