應用MESY*CYU電算程式系統進行結構線性自動化分析

Automatically Linear Structural Analysis by Using MESY*CYU Program System

指導教授 : 王寶璽

摘要


本文應用有限元素法電算程式系統MESY*CYU建立二維結構線性自動化分析模式,可執行二維結構線性靜力、線性挫屈、線性化二階靜力、頻率振態及線性動力反應等分析工作。MESY*CYU電算程式系統中之MESYGEM副程式組是用以執行結構分析資料自動輸入、輸出工作,將結構的幾何尺寸、材料性質、外力荷重等資料輸入,並以固定的格式輸出,可供列表、繪製成圖。本文延用原MESYGEM副程式組,增加多個副程式強化其功能,使其不但可做分析資料自動輸入、輸出的工作,還可進行自動化結構分析計算。 文中說明自動化分析程式架構、計算流程,與原MESY*CYU電算程式之差異,資料輸入格式,應輸入的數據,並取多個不同型式的結構為例,說明自動化分析程式如何運作,分析的模型如何取決。此結構線性自動化分析程式可成功的應用在線性結構分析上,將原MESY*CYU結構電算程式系統中手算的工作量完全排除,大幅增加結構分析的效率。

並列摘要


A finite element program for automatically linear structural analysis based on MESY*CYU program system is conducted in the study. The program composed of both linear structural analysis and MESYGEM subroutines. Five types of two-dimensional problems i.e., linear static analysis, linear stability analysis, vibration frequency analysis, linear dynamic analysis and linearized second order static analysis can be solved by using the proposed program. Seven examples are also addressed to clearly illustrate the five problems. The MESY*CYU-based program can significantly improve the effectiveness of structural analysis.
