Abstract

Abstract: To solve the ground equivalent test problem of the airborne launch system, an optimization method for the dynamic characteristics of the ground launch rack test system based on a multi-variable optimization approach was proposed. Through the discussion on the boundary conditions of the foundation, an effective dynamic simulation model of the ground launch test system was established. By comparing the dynamic characteristics of the launch rack structure in the airborne state and the ground test state, the objectives and constraints of the optimization design were determined. The dynamic characteristics of the ground test system were optimized and designed. The results show that this method can effectively optimize the dynamic characteristics of the launch unit in the ground launch test system to be close to those in the airborne state and reduce the peak dynamic response of the test system during launch impact. This method can be effectively extended to the dynamic characteristic optimization design of various ground launch test systems and enhance the effectiveness of ground test verification for airborne weapons.
