Variable-Length Cable Dynamics of Payout and Reel-in With a Vertically Tethered Underwater Drill Rig
Mens Skirts A new dynamic model of the variable-length cable used in a vertically tethered underwater drill rig is presented in this paper, which also includes the dynamics of its fixed-length counterpart.First, the differential equation of the variable-length cable is derived through the theorem of linear momentum, and its finite element formulati
