摘要
近些年来,齿轮减速器在现代工业社会得到的广泛应用,随之产生的噪声也影响着人们的生活质量。本文以JZQ减速器为研究对象,计算其啮合频率并借助ANSYS分析减速器的固有频率,并通过压电阻抗实验验证了减速器产生振动噪声的原因。利用ANSYS中的声学分析模块通过对改变减速器壳体厚度后声压级的变化的分析,证明该方法可实现有效的降噪,为减速器噪声优化提供一种较为简单的方案。
In recent years,the gear reducer has been widely used in modern industrial society,and the ensuing noise has also affected people's quality of life.This paper takes the JZQ gearbox as the research object,calculates its meshing frequency and analyses the inherent frequency of the gearbox with the help of ANSYS,and verifies the causes of vibration noise generated by the gearbox through piezoelectric impedance experiments.By using the acoustic analysis module in ANSYS to analysis the change in sound pressure level after changing the thickness of the reducer shell,it is proved that the method can achieve effective noise reduction and provide a simpler solution for reduce noise optimization.
