| Abstract: | Based on nonlinear vibration theory, vibration prediction method is established.By testing and analysis of air-conditioning vibration, the main relevant influence factor and main excited vibration source of air-conditioning are found.There is taking a targeted improved measure that eliminating the semi-rigid connection between structures by setting vibration isolation device.The natural frequency of ocean platform structure is changed and apart from the resonance area.The method gets obvious good effect on ... |
