摘要
引入Logistic混沌模型和最优蚂蚁保护策略对蚂蚁算法进行了改进。对再现连杆角位移的平面连杆机构,分析了其运动精度的影响因素,建立了模糊稳健优化设计数学模型。给出了基于蚂蚁算法的模糊稳健优化设计实例,在求解机构杆长等参数的同时,还求出了各杆长的制造公差,保证了机构运动精度的稳健性。
The basic ant colony optimization algorithm was improved by introducing the Logisti-chaos model and a strategy of protecting optimal ant.The factors influencing movement precision were discussed in the design of plane mechanism generating angle-displacement of connecting-bar.The fuzzy robust design model was established,and a fuzzy robust design example of plane mechanism generating angle-displacement was given based on ant colony algorithm.When the design parameters including the rod-lengths of plane mechanism were solved,the manufacture tolerances of each rod of mechanism were determined.The robustness of motion precision can be insured by the new fuzzy robustness method put forward.
