| 摘 要： | 应用遗传算法,并对基本遗传算法进行相应的改进,对空间桁架结构截面进行优化。在应用遗传算法的同时,考虑满应力解通常处在最优解附近的原理,将满应力解作为种群中的一个个体参与计算,并通过MATLAB编制相应的程序实现。算例表明,该方法能得到理想效果,并减少程序运算时间。

| Abstract: | A method based on modified genetic algorithm(GA) is developed for the optimum design of space truss structureThe full stress solution is added to the GA method considering the principle that the full stress solution is near by the optimal oneA space truss structure MATLAB program was designed based on this methodThe example shows that the method can get ideal results and reduce the operation time |
