摘　　要：主要研究平面连杆机构函数综合问题。根据平面连杆机构函数综合的特点和优化的思想,以杆长和初始角作为设计变量,转角误差和约束条件构造代价函数建立机构优化的数学模型。通过研究差分算法,提出了一种基于差分算法的平面连杆机构函数综合优化设计的新方法。该方法与其它的智能优化设计方法相比较,算法简单,收敛速度快,所需领域知识少,比较适合于解决复杂的优化问题。最后设计实例表明了该方法的可行性和有效性。The paper it study function synthesis of planar linkage mechanisms by optimization design method.According to the characteristics of optimization design,the mathematical model of mechanisms optimization is established,with the length of bar and original angle as design parameters,constraint and error between theoretical and practical angles as cost-function.By above-mentioned idea,a new optimization method based on differential evolution for function synthesis of planar linkage mechanisms is developed.Differential evolution has some features such as simple to use,fast convergence speed and need little information about problems.Through researching,we found it is very suitable to solve some complex optimization problems.The design instances showed that the method was practicable and effective.
