Modern Approaches For Modeling Of Structure-Borne Noise Of The Internal Combustion Engine
Keywords:engine noise, structure-borne noise, noise modeling, AVL EXCITE, noise source
The article considers the structure of acoustic radiation of an internal combustion engine and modern technologies for noise research. Models of the internal combustion engine as a source of noise and methods for modeling the design and calculating the structure-borne noise of the engine at different stages of its design are described. The method of the engine structure-borne noise calculating for unsteady operation mode is presented. Differences in the working process of the engine for the transient operation mode are shown. Some results of calculations of diesel engine structure-borne noise for different operation modes using MADI methods and using the AVL EXCITE software are presented
