Analysis and Optimization Design of Air Defense Missile Back-blast Damage to Containers
Aiming at the problem of container damage caused by missile back-blast during missile launch,the unidirectional fluid-structure coupling method was used by the ANYSYS finite element cal-culation software for research and analysis based on the structural composition of containers and the operational condition of missile back-blast.It was concluded that the temperature of missile back-blast was the root cause of container damage,where the container cover could not withstand the impact of the missile back-blast which was the direct cause of container damage in the missile launch process test.The optimized design scheme for containers was proposed,and two measures were taken to increase the heat insulation plate and strengthen the structural strength of container covers.The effectiveness of the optimized design scheme was analyzed through finite element software simulation calculation.The de-sign of the test scheme was carried out,and the reliability of the optimized container cover to solve the problem of container damage caused by missile back-blast impact was verified by test.
