Embodiment 1

[0036] Design the tail drum of a three-purpose tugboat with a bollard drag force of 150 tons, the main parameters, the design load is 350 tons, and the length of the tail drum is 4000mm.

[0037] According to step 1 of the content of the invention, the formula for calculating the thickness of the cylinder shell is as follows,

[0038] t = Q 4 [ σ ] + ( ( Q 2 ) 2 + 0.48 Q 1 [ σ ] ) 0.5 / ( 2 [ σ ] ) ,

[0039] Accord...

Abstract

The invention discloses a stern roller design method of an anchor handling towing supply vessel. The method comprises following steps: calculating the thickness of a roller enclosure according to a load, an allowable stress and assumed roller radius and stiffener interval; calculating the size of the axial stiffeners of the roller according to the load and assumed roller radius; calculating the size of the circular stiffeners of the roller according to the load and assumed roller radius; carrying out optimization design through taking the roller radius and the stiffener interval as variables and taking the weight of the roller as an object; and determining the final roller design scheme according to the optimization result. The method of the invention is advantaged by simplicity, effectiveness, simple method, improving the working efficiency, greatly shortening the roller structure design time and effectively controlling the weight of the roller.

Description

Technical field: [0001] The invention relates to the field of ship design and construction, and particularly designs a simplified three-purpose working stern drum structure design method. Background technique: [0002] Anchorhandlingtowingsupplyvessel (AHTS for short) is a three-purpose guard vessel for deep-water operations that provides a variety of special operation services for offshore oil projects. and towing operations of large ships. [0003] When the three-purpose workboat helps other ships and offshore platforms to carry out anchor operation, the cable or anchor chain needs to be guided by the shark jaw and the tail drum. During operation, the tail drum will bear the corresponding load, so there are corresponding strength and rigidity requirements for the structure of the tail drum. The structural design of the stern drum has the characteristics of high strength requirements, nonlinear structure, and lack of strength calculation basis for classification societies...
