To solve the traditional fault diagnosis can not be adapted to the complicated system, a kind of new multi-sensor fusion fault diagnosis method is presented. The method applies the theory of genetic algorithms and fuzzy logic to the BP (back propagation) neural network. Combined with BP and GA, it walks in several steps. Firstly, the best individual is chosen in current population and trained in order...
Aimed at minimizing the centre distance of reducer in lift mechanism and being satisfied with the conditions of load-bearing capacity and distribution of transmission ratio, the mathematical model in fuzzy design optimization was set up which was to considering the random character of the value of design parameters. Firstly, the number of teeth of the minor gear in the system, its normal module, and...
