Modeling and Experimental Correlation of Pickup Box Drum Drop Test 2003-01-0604

Pickup box drum drop test is critical in vehicle development to determine the impact strength of the floor panels. Physical hardware tests on prototypes have been used to assess whether the performance of the future pickup box meets design requirements. In order to reduce costs and shorten development cycle, CAE methodology was developed to accurately model the drum drop test.
In this paper, a CAE procedure for modeling the drum drop test is proposed. Dynamic explicit finite element code LS-Dyna was used to simulate the non-linear impact process of a drum onto the box floor. The permanent plastic damages on the floor panel were recorded in both simulation and experiments. Very good correlation between the simulation results and the physical hardware tests was achieved. It indicates that the methodology developed is an effective tool in evaluating the performances of the pickup box floor panels.
