摘要/Abstract

摘要： 通过分析汽车同步带传动噪声产生机理,指出啮合冲击噪声和横向振动噪声是汽车同步带传动噪声的主要声源。基于声阵列测量原理为ZA型汽车同步带设计了传动噪声试验装置。通过不同转速的噪声试验得到了噪声声压分布云图和传动噪声频域特性曲线,验证了汽车同步带噪声产生机理和声源位置。试验结果表明,声阵列技术用于汽车同步带传动噪声源识别准确、可靠,本研究为汽车同步带传动的噪声控制提供了理论依据。

Abstract: Through the analysis on the noise generation mechanism of vehicle synchronous belt transmission,it is pointed out that the main noise sources of vehicle synchronous belt transmission are meshing impact noise and transverse vibration noise. A transmission noise test device for ZA type synchronous belt is designed based on the principle of sound array measurement.Noise tests are conducted at different speeds and the sound pressure nephogram and the frequency characteristic curve of noise are obtained,with the noise generation mechanism and sound source location of synchronous belt verified.The test results show that the noise source identification of vehicle synchronous belt transmission by using sound array technology is accurate and reliable.This study provides a theoretical basis for noise control of vehicle synchronous belt transmission.
