机械结构模态分析动画显示技术及其软件的实现

ANIMATION DISPLAY AND SOFTWARE TECHNIQUE FOR MECHANICAL STRUCTURE MODAL ANALYSIS

根据模态分析理论和计算机原理,论述了在微机上实现结构的实模态和复模态振型的劝画原理,推导了三维图形的窗视口变换的计算公式,并开发了CGE400显示器的高分辨率彩色图形的显示功能及80287协处理器的浮点运算助能,用汇编语言与编译BASIC语言编制了一套软件系统。

This paper concerns with the principle of animation display for mode shapes On monitor of micro-computer. Based upon the theory of modal analysis and computer science we have derived the evaluation formular for window transformation of 3-dimentional figures. High resolution coloured function of CGE400 display and floating point operation function of Intel-80287 Co-processor have also developed. By using the assembly and assembler-BASIC language a software system has been compiled which was applied to study modal analysis for a real world mechanical structure with success.
