Research on Optimization Design of Vibration Reduction Parameters for Launch Devices
To improve the impact resistance of the launch device landing,this study establishes a dynamic model and uses finite element simulation to verify the accuracy of the dynamic model by simulating the dynamic response of the projectile under the same impact load.Furthermore,the particle swarm optimization algorithm is used to optimize the parameters of the vibration reduction system of the launch device,selecting structural stiffness and damping as optimization variables to minimize the peak dynamic response of the projectile.The optimization results indicate that adjusting stiffness and damping appropriately can significantly reduce impact overload and vibration amplitude,effectively optimizing the dynamic response of the projectile under impact load.This study can provide scientific basis and direction for the design of launch devices and the optimization of their vibration reduction systems.
