The relationship between sound pressure and frequency of radiation sound field in the boundary element of pressure swing adsorption oxygen generator is analyzed by using ANSYS grid and acceleration. Damped boundary conditions, frequency range of 10-250Hz, frequency in increments of 2Hz, support PA reference sound pressure for 2XL, determine the location of the sound source at the oil-free compressor position. The sound pressure frequency curve of PSA oxygen generator noise was analyzed by using acousto-structure coupling model with oxygen in the center and side front of the casing respectively.

广州制氮机厂家分析表明，制氧机壳的网站出现在03,5470110hz峰值压力，和动态响应的峰值频率接近壳，声压和对应点的动态响应有着密切的联系。

总之，让我们对声场的声辐射制氧机的边界元分析的声压和频率之间的关系的进一步了解，同时产业和产品也有了进一步的研究。变压吸附制氧的真正的知识来自于实践，以指导实践，所以我希望你积极分享他们的知识和经验。
