Abstract
The large vibration problem of a designed air-conditioner pipeline system is studied.The Hyper Mesh software is applied to divide the designed air-conditioner pipeline model into a refined hexahedral mesh.Then,the model is imported into Ansys to carry out modal analysis,and the natural frequencies and modals of the first 10 orders are calculated.It is found that the first order natural frequency is near the operating frequency.Based on the analysis of the corresponding vibration mode,an improvement scheme is put forward for the pipeline system so that the first natural frequency of the air conditioning pipeline system can keep far away from the operating frequency to avoid the resonance.Finally,the experiment is carried out for the improved structure,and it is found that the amplitude of the vibration of the improved structure is reduced by 90 ％.The practice shows that the application of Ansys and the finite element technology can effectively improve the efficiency and accuracy in vibration reduction of air conditioners.关键词
