Simulation and Analysis on the Dynamic of a Missile Launch Canister

摘要

The vibration response of the launcher is one of the important sources of the initial disturbance of the missile launch. Based on the theory of multi-body dynamics and finite element analysis, a rigid-flexible coupling model of a vehicle-mounted missile launcher is established, and the vibration response of the launching tube is simulated. Using the method of replacing the rigid and flexible body models of the key components, the order of the main factors affecting the subsidence of the launch tube is obtained, and the conclusion that the subsidence can be reduced by increasing the rigidity of the frame and chassis is proposed.
