Hinge and Pin Stress Analysis as a Function of Barge Opening Angle on Split Hopper Barge

Abstract

An important construction to note on a split hopper barge ship is the hinge pin on the deck that connects the two sides of the hull. This is because the role of the hinge pin is very vital, so damage or failure of the hinge pin will result in failure of the entire barge. This study aims to analyze the stress, strain, and deformation in hinge and pin construction. Modeling and calculations are carried out using the ANSYS workbench software. Based on the results of the analysis on hinge and pin construction, it is found that the greater the angle of the barge opening, the value of the XY shear stress, XY shear strain, and the normal stress in the X direction will also increase so that the critical point for shear stress is at the maximum barge opening, which is an angle of 20°. For von-Mises stress, von-Mises strain, and normal stress in the Y direction, the larger the barge opening angle, the smaller the stress and strain values, so that the critical point for the von-Mises stress and Y-direction normal stress occurs when the barge is closed, namely 0° angle. As for the total deformation, the maximum value for the hinge is at an angle of 15° and the pin is at an angle of 10°, but the deformation values ​​for the hinge and pin construction are almost uniform and there is no significant deformation change.
