Fuzzy Comprehensive Assessment of Two Wheels Pair Parallelism on Metro Bogie
Under static load, metro bogie H beam and 1st hanging device transformation directly influence train travel attrition situation, if transformation is too big, it will probably cause train digression. The author established parallel parameter models and adopted fuzzy comprehensive assessment, regarded wheel pair angle, maximum and minimum distance, nodding and slant parameters as factor collection, regarded fully excellent, good, medium, qualified, worse, bad and very bad as selected factor collection, so that obtain parallel degree index of project practical value by fuzzy calculation.
