Title:
吊荷の動揺推定方法
Document Type and Number:
Japanese Patent JP7328910
Kind Code:
B2
Abstract:
To provide an oscillation estimating method of a suspended load capable of estimating oscillation of a suspended load in a semi-submerged state, suspended by a crane installed on a floating body.SOLUTION: An oscillation estimating method of a suspended load calculates the fluid force that a floating body 1 receives from a wave W, the force that the floating body 1 receives from a surrounding water mass when it oscillates due to the wave W, the fluid force that a suspended load 4 in the semi-submerged state receives from the wave W, and the force that the suspended load 4 in the semi-submerged state receives from the surrounding water mass when it oscillates due to the wave W using wave information in the target water area where the floating body 1 and the suspended load 4 suspended by a crane 2 installed on the floating body 1 are arranged. The method estimates the oscillation of the suspended load 4 in the semi-submerged state in the target water area based on the calculated forces that the floating body 1 and the suspended load 4 receive respectively and the equation of motion for the coupled motion of the floating body 1 and the suspended load 4.SELECTED DRAWING: Figure 1
