Abstract

The purpose of this study is to develop the optimum shape of blank for the crank throw of large marine engine in order to reduce manufacturing cost and forging defects. The effects of the curvature radius and the height of wing part of blank selected as design variables on the defects and machining margin of final products after forging process were investigated using FEA. Based on the results, the optimum shape for the blank of the crank throw was proposed and verified by experiment.
