复合材料空间薄壁组合结构的静动力分析

Analysis of the Strength and Dynamic Response Characteristics of Composite Laminated Space Thin-Assembled Structure

本文采用了以混合标架法为基础的复合材料经典层合理论的有限元法分析了复合材料空间薄壁箱形结构在静力和动力作用下结构的刚度特性、强度特性、振动特性和破坏特性,在程序上应用了高效的JINEGS内存管理系统,使得该程序在微机上(IBM—PC及其兼客机)能分析较大的复合材料空间薄壁组合结构的静动力响应问题。文中通过对典型数例计算结果的讨论,得出了一些具有工程实际意义的结论。

The present paper, by using mixed-coord in ate technique,gives a finite element, method on basis of classical laminated theory for investigating stiffness strength and dynamic response characteristics of composite laminated space thin-walled box-beam structure.A core management system with high efficiency 'JINEGS' was employed in computer code 'FKBXJ' to solve composite laminated complicated space box-beam struture analysis problems.Several numerical examples were given in the paper. From discussion about the numerical results. The conclusions were obtained, which is benefit to engineering analyst and designer for composite laminated structure.
