基于遗传算法的平面并联机构运动学设计

Kinematic design of planar parallel mechanism based on genetic algorithm

针对平面并联五杆机构提出了基于总体灵活度的运动学设计方法。该方法将运动学设计问题归结为全局运动性能指标最大为目标的单目标有约束优化设计问题 ,并采用遗传算法搜索到一个最优解 ,将其与采用随机方向法所得到的解进行比较 。

Directed against planar parallel 5-bar linkage a met hod of kinematics design based on overall flexibility was put forward. This method summed up problems of kinematics design as problems of single aimed restraint optimum design which takes the target of overall kinetic property as a maximum goal. An optimum solution was seached out by adopting genetic algorithm, when compared with the solution obtained from using random directional method, the result of comparison shows that the genetic algorithm has obvious advantages.
