To completely avoid producing elements jointed at their corner nodes and checkerboard patterns , which frequently occur when the topology optimization of plane continuum is studied , the theory of topology analysis of plane continuum in topology optimization process and the simple algorithm for programming are studied . according to algebraic topology theory , the boundary of elements and plane continuum are operated as a one - dimensional complex . by use of the adjacency vector in graph theory , the structural topology is described and the topological operation is achieved on a computer . by above , the structural topological feature in the evolutionary process is gained . these methods are effcient and reliable . under topology constraints , according to the results of stress analysis , by deleting elements and moving nodes at the boundary , more satisfactory results can be gained by using a few numbers of elements and iterations . to demonstrate the efficiency of these methods , solutions including some well - known classical problems are presented 避免目前平面連續(xù)體結(jié)構(gòu)拓?fù)鋬?yōu)化過程中經(jīng)常出現(xiàn)的單元鉸接以及“棋盤格”等現(xiàn)象,研究了連續(xù)體結(jié)構(gòu)拓?fù)鋬?yōu)化過程的拓?fù)浞治龇椒?,以及在計算機(jī)上實現(xiàn)的簡便算法.根據(jù)代數(shù)拓?fù)淅碚摚瑔卧斑B續(xù)體的邊界作為1 -復(fù)形進(jìn)行運(yùn)算.利用圖論中的鄰接向量概念,在計算機(jī)上實現(xiàn)了結(jié)構(gòu)的拓?fù)涿枋黾巴負(fù)溥\(yùn)算,得到了結(jié)構(gòu)在拓?fù)溲莼^程中的拓?fù)涮匦裕椒ê唵?、可?在一定的拓?fù)浼s束下,根據(jù)應(yīng)力分析結(jié)果,采用刪除單元、單元退化、移動節(jié)點等方法,可以用較少單元得到更為滿意的結(jié)果,提高計算效率.為演示方法的有效性,給出幾個包括常見經(jīng)典問題的解答
