PSO is a population-based optimization algorithm, which mimics the social behavior of animals in a flock. It makes use of individual and group memory to update each particle position allowing global and local search optimization. The objective function considered was the total weight of the structure subjected to stresses, displacements and forces constraints. The effects of the parameters were investigated as well and such combination of tuning parameters promote a better global search behavior avoiding premature convergence while rapidly converging to the optimal solution. Results showed the effectiveness of the proposed method by comparing with ANSYS Design Optimization Tool (zero-order method). The PSO with the tuning parameters makes it an ideal method for offshore wind turbines foundations optimization tasks.(2) A reliability analysis method for pile foundation bearing axial loads based PSOThe performance function of pile foundation's axially bearing capacity sometimes is nonlinear and complex, on the basis of geometric meaning of structural reliability index, an optimum model with PSO for structural reliability analysis under arbitrary random variables was established, The PSO algorithm is very efficient to solve global optimization problemsIts use in structural reliability field presents not only the advantage of its facility of implementation, but also the possibility to obtain the design point and the failure probability with a good accuracy. In addition, PSO is a zero order algorithm, for no derivative is necessary for its implementation.
本文的研究针对桩式海上风机基础结构的特点,在国内外有关研究成果的基础上对海上风机基础结构优化设计理论和可靠度方法一些相关问题进行了较为深入的研究,具体做了以下几个方面的工作:(1)基于粒子群优化的桩式海上风机基础确定性优化设计方法桩式海上风机基础的优化设计是一个复杂的、非线性约束的优化问题,针对传统的基于梯度信息的优化方法在处理非线性问题中易陷入局部最优解的问题,本文将一种耦合惩罚函数的PSO算法引入到海上风机基础结构概念设计中,PSO算法是从群体动物聚集觅食这一活动中受到启发而发展的,该算法利用个体和群体的信息共享不断改进自身的位置从而进行局部和全局最优搜索,本文中以桩和三脚架连接段直径及壁厚为设计变量,以基础总重量作为优化的目标函数,在给定的约束条件下建立了三脚架基础优化数学模型,另外本文还研究了PSO参数变化对结果的影响,协调的参数组合可以避免陷入早熟收敛而能够快速的获得全局的最优解,通过与ANSYS优化模块的计算结果比较验证了该方法的有效性,本方法为海上风机基础的确定性设计提供了一条有效的途径。
