- Hopper Slopes in the Cargo Holds of Self-unloading Ships
説明
In order to estimate the main hopper side slope in the cargo holds of self-unloading ships, a triangular, rigid, powder block was assumed at the transition of the walls of the cargo hold. When a given size of the powder block just slid off the hopper walls, the critical hopper slope was calculated from the force balance on the powder block.<br>The calculated critical hopper slope increased with a decrease in the size of the powder block, and a maximum value was obtained when the powder block became infinitely small. For the desigh of the cargo hold, this maximum value was taken as a lower bound of the main hopper side slope.<br>When assuming that the cargo hold is for carrying coal, the calculated hopper slope was 40°against an ulrta high molecular weight polyethylene plate, and was 51°against a steel plate. These calculated results were slightly large in comparison with the main hopper side slope adopted in the cargo holds of existing self-unloading ships. Consequenty, a low hopper slope required both a low frictional coefficient and a low adhesive force between the powder and the wall material of the hopper.
