摘要
Purpose This study aims to accurately evaluate the influence of various error intervals on the performance of the wiper. Design/methodology/approach The wiper structural system is decomposed into classical four-link planar for kinematics analysis, and it was modeled respectively by using interval method, universal grey number theory and enumeration approach depending on the nature of uncertainty. Findings The universal grey number theory is a viable methodology for the accurate analysis of uncertain structural system. Originality/value (1) The model of uncertain wiper structural system is established. (2) Universal grey number theory and new parameters are adopted to analyze the presence of uncertain wiper structural system. (3) Comparative analysis of response quantities is obtained by interval method, universal grey number theory and enumeration method.
