An Analyze of Fatigue Life Construction of Lifting Poonton for Small Vessel
Abstract:
Developing prototype aluminum pontoon lifting that functions as a floating dock for the repair of small vessels. To ensure the safety aspects of the construction of the Poonton lift, structural analysis is carried out. The purpose of research to determine the strength and fatigue life construction of lifting ponton due to loads. The method used is the finite element method and the palmgren-miner method. This research uses finite element based software. The results showed that the maximum stress value in the construction of the lifting pontoon is (σmax) = 74,897 MPa which is located in the H-Beam construction that functions as a supporting. The estimated fatigue life of the poonton lifting analyzed during operation is 9.46 years with a total load cycle of 1111680 cycles.
