An aerospace structure complex pulse impact response analysis method and system

Abstract

This invention proposes an analytical method and system for the complex pulse impact response of aerospace structures, belonging to the field of aerospace structural dynamics analysis and design. The method includes: obtaining the structural parameters and pulse load parameters of the high-order elastic structure in aerospace and performing standardization; constructing a fundamental mathematical model of the boundary value problem of the high-order differential equations, substituting the standardized parameters into the corresponding terms of the fundamental model to obtain a parameter-determined model; solving the parameter-determined model based on variational methods and functional analysis, defining the solution space and displacement norm, constructing and decomposing the energy functional, and solving the energy functional to obtain the classical solution of the displacement response parameter-determined model; performing dynamic analysis based on the classical solution, and outputting an analysis report to provide a basis for structural strength verification and impact-resistant design. This invention achieves accurate solutions for the dynamic response of high-order elastic structures under complex pulses, providing a reliable theoretical and engineering basis for the impact-resistant design of aerospace structures.
