摘　　要：分析了平面StephensonⅢ六杆机构综合的现状 ,综合各种优化方法后 ,对混沌算法和遗传算法的混合进行了分析。利用混沌运动的遍历性、内在随机性、“规律性”以及对初值的敏感性等特点 ,结合遗传优化算法 ,提出了混沌遗传算法。运用MATLAB6.1高级程序设计语言编制了计算程序 ,对平面StephensonⅢ型六杆机构的函数发生器综合 ,从而找到了实现最大精确点时该问题的一批有意义的解 。At the first, the author systematically analyzed the existing states of the planar Stephenson III synthesis and features of various optimization methods. After the hybrid problem of genetic algorithm and the chaotic optimization algorithm were discussed in detail, a chaos genetic optimization algorithm was proposed by the use of the properties of ergodicity, inherent stochastic property,'regularity' of chaos and strongly sensitivity to initial value. The programming was compiled with Matlab6.1 programming language. The problem of function generation for Planar StephensonⅢ six-link Mechanism was solved by this optimization method , and thus meaningful solutions for this problem with maximum precision positions were obtained for the first time.
