中文摘要:
      研究了阻尼防振锤对深水导管架圆管风致涡激振动的抑制。建立了防振锤动力学模型,分析了防振锤的动力学特性;将在建深水导管架圆管简化为固支梁,建立了结构有限元模型,通过瞬态分析计算了圆管的振动幅值;在圆管中部添加防振锤,分析了防振锤对圆管振动的抑制效果;进行了现场测试,对比了数值模拟和实际测试管道的振动响应。研究表明,文中设计的防振锤可以有效地抑制圆管的涡激共振;数值模拟结果与测试结果非常接近,验证了数值分析方法的有效性。
英文摘要:
      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.
