摘要: 以連桿角位移再現平面四桿機構為例,討論了其設計變量、噪聲因素以及質量特性和目標函數的確立過程,建立了基于容差模型的角位移再現機構的穩健優化設計數學模型;給出設計結果,并與原方案進行了比較.結果表明,該方法在保證機構運動質量穩健性的同時,可以獲得更大的設計變量容差,從而提高機構的可制造性,降低成本.Abstract: As an angle displacement generation mechanism for example, the process of choosing design variables, noise factors and quality targets was given. A mathematical model of robust design for angle displacement generation based on the tolerance was established. The result of design was given and compared with that of the original projects. It is shown that the robustness of movement precision can be insured and the larger tolerances of each rod of the mechanism can be determined by this method, so the manufacturability can be improved and the cost can be reduced.
