Structural Design of Umbilical Cable and Sea Trials of Wave Glider
Taken the"Pioneer"wave glider as an example,its structural composition and performance are introduced,focusing on the detailed design of flexible armored cable,junction box and buffering and damping structure in the umbilical cable structure.The armored cable with a NACA like airfoil as the cross-section is studied,which reduces fluid resistance by 40％compared to that of the traditional flat cable.Two 3.5 mm steel wire ropes of the armored cable are connected to the junction box through fixed pressing plates and winding columns,providing a bearing tension of approximately 9 994 N.The buffering and damping structure based on combined belleville springs can buffer and absorb approximately 115.6 J of impact energy,ensuring that the umbilical cable structure can withstand the periodic loads generated under the eighth level sea conditions.A 69 d sea trial is conducted in the South China Sea,with a navigation distance of 2 383 km,an average speed of 1.28 kn under the third level sea conditions,and a virtual anchoring accuracy radius of less than 80 m,verifying the sea navigation performance of the wave glider.
