For the problems that it is easy to generate plastic deformation in the process of placing the parts on the receiving platform by the automatic feeding device with cantilever for the automobile cover part with large sizes and weights, and the drop deformation of side wall inner panel was simulated and analyzed by software Dynaform to determine whether there was the deformation risk of parts during the development stage of vehicle. First, the Dynaform model and simulation were conducted by the original digital model, and the accuracy of analysis was verified by similar parts. Meanwhile, the risk area of part was designed and optimized by adding stiffener, and the drop process of optimized part was simulated and analyzed. Furthermore, the effectiveness of the drop simulation was verified by the actual cases. Thus, the drop deformation simulation can evaluate whether the plastic deformation occured when the parts are received on-line in the synchronous engineering stage, so as to optimize the design in time, avoid the engineering changes in the later stage and reduce the development costs.
