摘要
针对高空作业平台调平铰点优化问题,根据油缸的同步反向原理,建立以调平三连杆机构参数为设计变量、最小调平误差为目标函数的多变量优化数学模型。适应度函数参数选择引用模糊子集,将改进的遗传算法应用于机构优化设计中。该算法群体搜索能稳定收敛得到全局最优解,提高了进化速度和精度。优化结果和回代仿真表明该方法的可行性和有效性。
Considering the facts that optimization of the hinge point of leveling of aerial work platform,a multu-objective optimization mathematical model was established of using the parameters of three linkage of leveling as design variables and the smallest error of leveling as the objective function,according to the principle of cylinder of synchronization and reverse.Fuzzy sets were adopted by fitness function parameters and the improved genetic algorithm was applied to optimal design of mechanism.
