Abstract

The invention relates to a generator set shock absorption and noise reduction method based on noise source recognition. The method comprises the steps that a preset noise source is collected, a presetmatrix is established, and a noise reduction plan is preset; a noise detection module is arranged, and a noise monitor is connected with the corresponding position of the generator set; operating thegenerator set, detecting noise and establishing a detection matrix; comparing the detection matrix with a preset matrix; and selecting a corresponding noise reduction plan according to the detectionresult. According to the invention, different types of standard noise sources are pre-recorded; taking the noise source as a judgment reference; according to the method, the preset matrix is set to store the specified parameters in the noise into the sound source library, the types of the detected noise can be accurately judged by sequentially comparing the detected noise with the preset noise, the specific noise reduction method is used in a targeted mode according to the types of the noise, and the shock absorption efficiency of the method on the generator set can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of noise detection and processing, in particular to a vibration and noise reduction method for generating sets based on noise source identification. Background technique [0002] A generator set is a machine that converts a certain form of energy into mechanical energy. Its function is to convert the chemical energy of liquid or gas into heat energy after combustion, and then convert the heat energy into mechanical energy through expansion and output power externally. According to the fuel used Different, common generating sets can be divided into gasoline generating sets and diesel generating sets. However, the existing generator sets have relatively poor shock absorption and noise reduction capabilities, causing the noise of the generator set to spread to the cockpit during operation, affecting the environment in the cockpit. [0003] Generator set vibration reduction and noise reduction is an important i...
