Acoustic solid coupling mode analysis of pressure swing adsorption oxygen generator by nitrogen manufacturer in Shenzhen

The vibration of the oxygen generator and the coupling of the fluid medium (air) in the oxygen chamber, the modal parameters, considering the coupling system show that the acoustic-solid coupling and the structural model are close to the natural frequency, linear increase, and the local vibration mode is basically the same, this paper mainly analyzes the dynamic response mode.

The vibration of oil-free compressor of oxygen generator is the main excitation source. Sinusoidal excitation force should be applied to the vibration of compressor in oxygen machine to study the oxygen reaction. At the central position of each piece of wall node in the PSA oxygen generator, the frequency response of the displacement and the energy value at each point are analyzed by the method, and the harmonic response is calculated by the (FUL) L and sparse direct solver (spasr) [21 excitation lower set].

对制氧机动态响应的有限元分析：

（L）各节点的振动频率是一致的，5859195hz 3的频率出现较大的波动，明显的915hz共振；

（2）在3个不同方向的振幅，其中前面板主要Z之后！振动；

（3）在对称振动的壁结构，在相似的情况下，变压吸附制氧机底部节点最大频率响应，

所以我们可以得出结论，底板是最大的板的振动，噪声。

总之，让我们的变压吸附制氧机的声固耦合模态分析和有限元动力分析有了进一步的了解，也有相关的产品和行业的深刻理解，但在实践中，多实践，多反思，将有更多的知识和经验与你分享。小编希望我们可以共同进步。
