How to evaluate the temperature of an active heave compensation (AHC) rope

摘要

How to evaluate the temperature of an active heave compensation rope.The method isThe next stepThat is,WireStrandDrawing the shape of the rope as a mixed structure obtained through the assembly of the helical constituent members in the hierarchy level of the rope itself andUnder the assumption of linear elastic behaviorUse the mechanical model of the strand to show the material properties of each wire andUsing a mechanical model of a rope that shows the combined load and imposed curvature combined operation, andA thermal model is used to evaluate the increase in temperature (TS) of the rope relative to the ambient temperature;Thermal modelFriction between strand or rope and sheaveAnd, having two main loss sources of friction between wire or strand, andIncrease in temperature (TS) of the rope obtained by the thermal model andThe step of comparing the threshold value with a predetermined temperature.
