| Abstract: | This paper firstly introduces the definition of dimensionless parameters and the theory of building a new one.Then on the basis of researching achievements of dimensionless parameters in recent years,a new dimensionless parameter is constructed with re-combinatorial optimization of obtained parameters using genetic algorithm for concurrent fault diagnosis of rotating machinery.Experimental result shows that the parameter has better recognition effect for the several concurrent faults listed in the paper and can be applied in the actual diagnosis. |
| Keywords: | dimensionless parmneters genetic programming concurrent fault |
