Abstract

Aimed at the heaving pitch coupling stability problem for underwater mooring monitoring platform under the action of a nonlinear flow field, the heaving pitch coupled equations of motion were established in consideration of initial stability height and drainage volume change; The stability transition curve of underwater mooring monitoring platform when the frequency ratio is different were obtained by application of Floquet theory, virtual quality standard method and deformation parameters method, studied the stability of weak parametric excitation characteristics, determine the stability and instability regions, and validate the characteristics by the time history response.
