Abstract

Abstract: The tendon is simplified as nonlinear beam, the equations of motion and boundary conditions of a Tension Leg Platform (TLP) with a single tendon undergoing planar motion are obtained using Hamilton’s principle; employing two different tendon models(nonlinear beam and massless elastic spring) under different flow field conditions, the difference of the dynamic response of TLP was investigated; it is concluded that when the flow field conditions are different, the difference of the dynamic response of TLP using two different tendon models are quite obvious. Finally, explaining the reason why the difference of the dynamic response of TLP is so large.

Key words

Tension Leg Platform (TLP) / tendon / nonlinear vibration / Hamilton’s principle / Morison equation
