摘要
Abstract
In order to solve the problem that the penetration fuse circuit subjected to a large overload shock will produce circuit vibration noise,the mathematic model between the penetrating impact vibration excitation and the circuit vibration noise response has been established in the paper.And a noise elimination method based on wavelet analysis has been proposed.The method in the paper uses the wavelet transform to analyze the impact exciting signal of the penetration fuse and uses the Gaussian function to fit the output vibration noise response signal of circuit.Then the correlation function between these two signals can be established.The output noise processing algorithm of circuit is designed for vibration excitation based on this.The simulation results show that the algorithm has obvious de-noising effect on the noise of the penetration fuse circuit caused by impact vibration.关键词
