1、引言齿轮系统具有周期性齿啮合的基本特性,也就是说,机械振动不可能完全消除。因此,要进一步减少齿轮噪音,必须准确地研究齿轮噪声的辐射过程,还必须考虑到噪声是由不同辐射机理的若干频率分量所组成的。但是辐射的本质由于受到轴承支座等零部件的干扰至今还未能弄清楚。同时,要想看到声源也是困难的。本文发展了一种应用声全息技术的新系统,用它可以显示出机器辐射声源的位置。同时,还探讨了声辐射的状态,轮齿啮合频率噪
1, Introduction Gear system has the basic characteristics of periodic tooth meshing, that is, mechanical vibration can not be completely eliminated. Therefore, to further reduce the gear noise, we must accurately study the gear noise radiation process, we must also consider the noise is composed of a number of different frequency components of the radiation mechanism. However, the nature of the radiation has not yet been clarified due to the interference of components such as bearing supports. At the same time, it is difficult to see the sound source. This article develops a new system that uses acoustic holography to show the location of the machine’s radiated sound source. At the same time, also discussed the state of acoustic radiation, tooth meshing frequency noise
