the optimal designed mathematical model of multi-gear parallel drive and transmission for a certain giant overload operation machine is established.In this optimized gear design
some vague string diagrams of input-output relationship as well as the neural networks fitting methods of discrete data are given
and then the optimizing calculation by applying genetic algorithm is conducted.The result shows that through the utilization of this method
not only the working efficiency could be promoted
but the result could also be reasonable and credible.
