This method was applied to the dimensionality reduction of multidimensional time series via projection pursuit technique for fuzzy clustering. According to the results of the classification and the extraction of fuzzy rules through best value projection, three types of fuzzy membership function were generated using trapezoid distribution method. Then the sample's credit level was determined according to the fuzzy approximability in computation.

To eliminate abnormity wear of tires in double-front-axle system of heavy truck, the kinematics and dynamics analysis method is set forth. On the base of the results for heavy double-front-axle truck load distributing and manipulate stability, tire uniformity load condition and deficiency steering characteristic condition of heavy double-front-axle truck are put forward. Steering trapezia space movement formula, double-swing-arm space movement formula and double-swing-arm movement formula in actual status of heavy double-front-axle truck are fetched. Optimization models of steering trapezia and double-swing-arm are founded and optimization arithmetics of transmission system in double-front-axle steering are compiled.
