Abstract
In this paper, according to the characteristics of the diesel engine vibration signal, the design for a class of adaptive generalized morphological filter is applied to the noise reduction of diesel engine vibration signal. After pre-processing the diesel engine vibration signal, then it is designed the shape, width and height of the structure elements. This paper, according to the characteristics of the diesel engine noise, chooses the semicircle structural elements and calculates the local maximum signal sequence and local minimum signal sequence so as to strike the height and width of the structural elements, then uses the gradient method to find the weight value adaptive. As a result, it will make noise reduction to achieve effectively, and the result has some superiorities compared with the traditional wavelet noise reduction.
