Abstract

On a Ro-ro ships, there is a connecting bridge between the mainland and the ship, namely the rampdoor, in addition to being a liaison between the mainland and the ship, the rampdoor also functions as a passage for vehicles and passengers to enter the ship. Therefore, the rampdoor construction will receive a lot of various loads, both static and dynamic loads during the use of ramp doors, where static loads will cause problems such as deformation and cracking, while dynamic loads that occur continuously will experience fatigue. In this study, the results of the analysis are useful for determining the level of strength and fatigue points that occur in the ramp door construction, and also the greatest stress generated in the ramp door construction based on the variation of loading. This analysis was carried out using finite element method with the help of ANSYS workbench software , and 15 tons. The results of the analysis obtained after conducting research with the help of the Finite Element Method are that the highest equivalent stress is obtained for minibuses of 163.66 MPa, medium trucks of 318.26 MPa, and trontons of 596.73 MPa. and after that we get the fatigue life of the rampdoor and get the results of the fatigue life of the rampdoor that was analyzed, namely for 13.6 months or 1 years 1 month 18 days.
