| 摘 要： | 粒子群算法(PSO)是一种基于种群智能的优化算法。由于其具有快速收敛和操作简单等特点,粒子群算法在工程、经济管理等诸多领域均得到广泛应用,成为近年来智能计算领域研究的新热点。首先介绍粒子群算法,进而提出对于惯性权重进行线性变化。利用改进的粒子群算法对实际工程桁架结构进行尺寸优化以提高经济效益,并提出合理的参数设置。数据对比分析结果表明,改进的粒子群算法对于桁架结构尺寸优化设计是可行的。 |
| 关 键 词： | 粒子群算法 桁架 尺寸优化 惯性权重 |

| Abstract: | The particle swarm optimization(PSO)is a kind of optimization algorithm based on swarm intelligence. The PSO algorithm has been widely used in many fields such as engineering and business management for its fast convergence and simple operation,etc.It has become one of the hottest issues in the intelligence computation recently.After introducing the basic theory of the algorithm in the article,a linear inertia weight changing model is formulated and it has been applied to the size optimization of a truss structure.The numerical example indicates the feasibility of the modified PSO in solving size optimization of truss structure. |
| Keywords: | particle swarm optimization algorithm truss size optimization inertia weight |
