基于粒子群算法的轨迹频谱综合法

Path synthesis of linkage mechanisms by spectrum analysis based on Particle Swarm algorithm

平面连杆机构轨迹综合的频谱分析方法减少了迭代求解过程中变量的数目,并且变量初值的选定规则简单,极大地减少了轨迹综合计算的复杂度,但寻求最优解的过程仍然使用传统的逐步迭代方法,因此也具有传统寻优法所具有的不足。论文引入粒子群算法对寻优算法进行改进,在原方法的基础上进一步提高了寻优速度和解的全局性。

The method of coupler-curve synthesis of linkage mechanisms by spectrum analysis can reduce the numbers of variables in the process of iterative computation so that it reduce the complex of computing.But it also easily run into the local optimum.In this paper,Particle Swarm Optimization algorithm is introduced to improve,so it can converge at the global optimum quickly.
