Taguchi-fuzzy-based approach for the sensitivity analysis of a four-bar function generator

摘要

This article aims to use the Taguchi method coupled with fuzzy logic on the tolerance sensitivity analysis of a four-bar function generator. Experiments designed by the Taguchi method were carried out for obtaining the mean and the maximum displacement variations of the function generator. By converting these two variations into a multiple performance index by means of fuzzy logic, the effect of each control factor on the mechanism quality was further analysed. The Taguchi method coupled with fuzzy logic was used to systematically analyse the effect of individual control factors on the displacement variations of a four-bar function generator from which the key dimensions were identified.
