Tóm tắt

In robotics technology, tolerance design is a part of mechanical design and determines the final product quality. The spatial dimensional chain problem of the parallel structure with component links having an active assembly and the closed link having a given error is a complex one. Determining the relationship between the end effector tolerances and component link tolerances of each leg in general form is the basis for digitizing the problem. Calculating the initial approximation of tolerance for other structures in the group based on the sample solution has the meaning of deciding time and quality of calculation. This paper proposes a hypothesis that it is always possible to determine a reasonable initial approximation based on a sample solution. Therefore, the process of calculating tolerances of the component kinematic parameters of parallel industrial robots is significantly shortened.
