| Abstract: | Due to the signal fault faintness and detection hard at the inception of pump cavitation,a new method named Parallel Recombination Simulated Annealing Algorithms is introduced.The principle and operation of the algorithm are presented at first.The characteristic parameters of the crust vibration and outer pressure signal on normal and fault conditions are extracted and analyzed based on the test bed to simulate the fault of pump cavitation,and then the new characteristic parameters are obtained by them usin... |
