해양환경을 고려한 150톤 윈치의 동특성 해석

Abstract

This paper concern about a dynamic analysis of 150 ton which with ocean environment data. Winch model for analysis is modeled from CAD to each subsystem by commercial software DAFUL. Winch model have tree brake systems disk brake,band brake and ratchet brake). Rotation motion of motor and contact elements of brake are applied to winch model for analysis of dynamic characteristics. Also crane-barge is modeled to apply a ocean environment data. Motion data of crane-barge is made by RAO of barge and wave spectrum. Reaction force of translational joint is measured instead of tension of cable. Brake performance of winch is carried out with operating motion of crane-barge.
