Simulation analysis and optimization of launch mechanics characteristics of comoposite launch tube barrel
The stiffness and strength response characteristics of a type of glass fiber comoposite launch tube barrel un-der missile launch conditions were evaluated by using finite element numerical simulation method.The helix angle of the spiral layer of the cylinder wall,the thickness ratio of the circumferential layer to the spiral layer and the thickness of the cyl-inder wall were used as design variables to optimize the design of the composite launch tube.The results show that the safety margin of the composite launch tube before optimization is low and does not meet the design requirements;the maximum dis-placement of the optimized composite launch tube barrel is reduced by 57.8％,the safety margin is increased to 0.27,and the design requirements are met,and the weight of the composite launch tube is 6.8％lighter than before optimization.The results of the study provide a reference for the design of the composite launch tube barrel.
