弹性缆对缓解电气承力缆型潜标环境响应的作用

Effect of Snubber Hose in Mitigating Environmental Responses of Electrical-mechanical Cable Subsurface Mooring

摘要:

针对电气承力缆型潜标（EMC-SSM）在极端海况下动态响应过大问题，建立了环境响应数学模型。通过某型电气承力缆型潜标在百年一遇海况下的拉力响应计算，研究了弹性缆在缓解电气承力缆型潜标环境响应方面的有效性及不同配置对缓解效果的影响规律。结果表明：长度适合时弹性缆对电气承力缆型潜标的动态响应具有显著的抑制作用，但不合适的长度将加剧其动态响应。最后，给出了弹性缆的设置原则和最短有效长度的确定方法。

Abstract:

A mathematical model of environmental responses for electrical-mechanical cable subsurface mooring （EMC-SSM） was established to solve the problem of the significant dynamic response of EMC-SSM under extreme sea conditions. The effectiveness of the snubber hose in matigating the environmental response of EMC-SSM and the effect of different configurations of the snubber hose on the mitigation were studied by calculating the tensile response of a specific type of EMC-SSM under sea conditions with a 100-year reoccurrence period. The results show that the dynamic response of EMC-SSM is inhibited with an appropriate length of snubber hose. However，the dynamic response of EMC-SSM is enhanced when the length of snubber hose is inappropriate. Finaly， the configuration principle of the snubber hose and the method for determining the shortest effective length were also presented.
