针对传统力密度法求解大规模、不规则张拉整体结构找形效率不高的问题，提出了一种力密度法与改进鱼群算法相结合的找形方法。先基于力密度法建立结构的平衡方程组，然后采用改进的鱼群算法在力密度空间内进行全局搜索最终来得到结果的算法，希望对大家有帮助-In view of the traditional force density method to solve large-scale, irregular tensegrity structure the problem form the efficiency is not high, and put forward a kind of force density method and improve fish algorithm combining fractal method. First based on the equations of equilibrium structure of the force density method, then USES the improved fish algorithm in space for global search eventually force density algorithm to get the results, I hope it can help you
