| Abstract: | The suppression of wind-induced vortex vibration of circular pipe of deep-water jacket by anti-vibration hammer is studied. A dynamic model of the damper is established, and the dynamic characteristics of the damper are analyzed. The circular pipe of the deep-water jacket under construction is simplified as a fixed beam, and a structural finite element model is established. The vibration amplitude is calculated through transient analysis. The hammer is added in the middle of the circular pipe to analyze its suppression effect on the pipe vibration. Field tests were conducted to compare the vibration response of the numerically simulated and actual test pipes. The results show that the hammer designed in this study can effectively suppress the vortex induced resonance of the circular pipe. The numerical simulation results are very close to the test results, which verifies the effectiveness of the numerical analysis method. |
