Lifetime simulation of traditional boat propellers using Ansys

Abstract

In this study an age-predictive simulation of propellers used by traditional fishermen in the Indramayu region was carried out. These boats were driven by gasoline or diesel motors to drive boat propellers. This boat propeller is made of aluminum alloy with gravity casting technique. The problem is that there are many fishermen who fail on their propellers which generally occur faults on the propeller fins, the purpose of this study is to predict fatigue and age of propellers used in traditional boats, with the observation and calculation method of Finite Element Analysis (FEA) using Ansys software. The results of lifetime propeller analysis with variability in boat hull loading and boat load, with different variations between 3488N and 4788 N, obtained a lifetime for the loading did not experience a significant difference with a lifetime of 277,7 hours.
