STRENGTH STRUCTURAL ANALYSIS OF THE SHAFT BRACKET PROPELLER ON FAST PATROL BOATS

Abstrak

Shaft Bracket Struts is located at the rear of the ship and used to shore up the shaft and propeller shaft tubes as well as have an impact on the work process with a high round power machine, if there is a problem on the strength of struts then there can work optimally. At this writing, done the analysis and deformation on the model stress shaft bracket original and three design models in modifications. The first stage is the collection of data such as propeller shafts and bracket dimensions, load that works and material shaft bracket bracket and propeller. Then do modelling and propeller shaft bracket on AutoCAD software. The Model is analyzed using the Finite Element Method (FEM) in Ansys Workbench Software. To find out the stress and deformation, then analyzing is done fixed conditions approach on Shaft Brackets Solusion, free on Shaft bracket, there is no displacement, displacement, 0.5 mm and 1 mm in area of the bearing. From the results of the analysis of the structure of stress and the resulting deformation, the biggest occurred in tension Shaft model V-Brackets 1 mm displacement of 241.68 N/mm2 and the smallest on the V-Bracket Solution there is no displacement of 56 N/mm2 at location on Shaft Propeller, while the biggest deformation occurs in V-Brackets 1 mm displacement of 137.82 mm and the smallest on the V-Bracket Solution 0.5 mm at happen of location on ship body
