水下连接器是海底井口之间连接的枢纽，同时也是采油树上关键的设备之一。水下连接器的振动来源于海流及波浪对海洋跨接管产生的涡激振动，因此为了研究水下连接器的振动，需要对跨接管的振动进行研究分析。首先对水下连接器所处海洋环境进行调研包括海流流速、海水运动粘度、密度、海水温度、弹性模数等物理性质，通过机械振动、海洋工程、工程力学等理论对水下连接器所受到的振动的振幅及频率进行计算。最后通过有限元分析软件ANSYS Workbench软件对水下连接器进行模态分析，得出其关键部件的各阶固有频率及振型，进而得出水下连接器关键部件涡激振动不会引起水下连接器的共振。

Subsea connector is the hub of the connection between the subsea wellhead, and also one of the key devices on Christmas tree. Vibrations of subsea connector from vortex induced vibration which currents and waves acting on jumper. The vibration analysis of jumper is in order to study the vibration of subsea connectors. First research the marine environment which subsea connectors located, including the current velocity, water kinematic viscosity, density, water temperature, elastic modulus and other physical properties. The amplitude and frequency calculation of vibration which subsea connectors suffered was through the theory of mechanical vibration, marine engineering, engineering mechanics. Finally, Modal analysis were conducted by the finite element analysis software ANSYS Workbench and draw its natural frequencies and mode shapes of key components. Conclusion the key components of an subsea connector’s vortex induced vibration would not cause subsea connector’s resonance.
