【摘要】：半結(jié)構(gòu)法是計(jì)算對(duì)稱(chēng)結(jié)構(gòu)的一種簡(jiǎn)化分析方法,通常應(yīng)用于軸對(duì)稱(chēng)結(jié)構(gòu).本文將探討半結(jié)構(gòu)法在中心對(duì)稱(chēng)結(jié)構(gòu)計(jì)算中的應(yīng)用問(wèn)題,包括中心對(duì)稱(chēng)、反對(duì)稱(chēng)載荷作用下結(jié)構(gòu)的對(duì)稱(chēng)性及其證明、等代結(jié)構(gòu)形式及其應(yīng)用等.算例表明,中心對(duì)稱(chēng)結(jié)構(gòu)半結(jié)構(gòu)法能夠最大程度簡(jiǎn)化結(jié)構(gòu)、提高結(jié)構(gòu)計(jì)算效率,與其他方法聯(lián)合應(yīng)用的一題多解方法可豐富結(jié)構(gòu)力學(xué)教學(xué)內(nèi)容,有利于學(xué)生拓展其創(chuàng)新思維及分析解決復(fù)雜力學(xué)問(wèn)題的能力.
[Abstract]:Half-structure method is a simplified analytical method for calculating symmetric structures, which is usually applied to axisymmetric structures. In this paper, the application of semi-structure method in the calculation of centrosymmetric structures is discussed, including centrosymmetric, symmetry and proof of structures under antisymmetric loads, forms of equivalent structures and their applications, etc. The numerical examples show that the centrosymmetric semi-structure method can simplify the structure to the greatest extent and improve the efficiency of structural calculation. A multi-problem solution method combined with other methods can enrich the teaching contents of structural mechanics. It is helpful for students to develop their innovative thinking and the ability to analyze and solve complex mechanical problems.
