摘要
应用遗传算法进行结构拓扑设计可以克服传统方法的诸多不足。本文应用遗传算法,采用基于“链码”的编码方式和数学形态学的变异算子,设计了一种连续体结构拓扑优化的新方法。此方法消除了棋盘格和铰接现象,提高了优化分析的效率,可以在较短的时间内找到优异的拓扑结构。
The application of genetic algorithms to comings of traditional methods. A novel algorithm structural topology design can overcome many shortfor topology optimization of continuum structures has been designed on the basis of ＂chain-code＂ encoding and mathematical morphologic operators. The new method removes checkerboards and hinges, produces crisp topology of structures, improves optimizatin efficiency and finds excellent topological structures within a short time.
