Effect of Load-Relieving Structure against Overload under High Overload

Abstract:

Three-dimensional visco-elastic lame deformation incremental constitutive equation is derived based on Total Lagrangian method, and structural dynamical response distribution in the grain during launching is simulated numerically by finite element method under high load condition for projectile-based equipment, the equivalent stress in the bottom of load-relieving structure and the Y-displacement in the top of load-relieving structure are calculated. The results show that the stress is ameliorated after the function of load-relieving subassembly, and it can decrease impact. Also Y-displacement is accord with limit request, and when reaching the maximum, the transmutation will be comeback.
