Judgement Research on the Dump Truck Frame Intensity-mass Relationship Based on Fuzzy Theory

摘要

During the frame optimization design, according to fuzzy integrated evaluation theory, fuzzy mathematical models of intensity coefficient and mass coefficient and intensity-mass ratio coefficient of dump truck frame were established. Based on those, in terms of Sugeno fuzzy discursion method, fuzzy discursion model about frame intensity-mass relationship rationality was established, too. Through checkout of three dump truck frames of 170t and 85t and 42t, validation results were the same as the fact. So, it was concluded that the fuzzy integrated evaluation model and the fuzzy discursion model gave helpful guidance on frame designing work.
