Size Optimization Design for Cantilever Structure of an Ammunition Supply Truck Based on Optistruct

Due to the narrow installation space of the ammunition supply truck, the cantilever structure is required to be light-weighted with the length of cantilever being limited. In this paper, the finite element model of the cantilever structure crane is established, through which the stress and displacement of cantilever structure in unloaded state and loaded state can be solved in order to analyze the possible failure location of cantilever structure Combined with the actual use of the cantilever structure crane, the scheme of size optimization based on Optistruct is proposed. The analyzed results of the optimized structural scheme indicate that the structure is 12.43% lighter than before meeting the stress requirements so that the cantilever structure crane is feasible.
