IMPACT SIMULATION ANALYSIS FOR FREE FALLING STATUS OF COMPOSITE TORPEDO SHELL

Abstract

Abstract: The drop processes of composite torpedo shell including free falling status, contacting with ground status, impacting on ground status and stressing status were simulated by the nonlinear material module of mechanical motion in ALGOR. The effect of ground and drop-posture on the composite torpedo shell during the dropping was investigated by simulating the four statuses respectively. Based on the comparison and analysis of simulation results, including force, stress, strain and displacement, the dropping resistance properties of torpedo composite shell were obtained, which was used to evaluate the impact performance of composite torpedo shell.

Key words: composites, torpedo shell, free-fall dropping, impact
