The analysis temperature using the finite element method for piston in engine of small sized ship

The analysis of temperature distribution is substantilly important in optimal design of engine. In this study, temperature analysis of the aluminum alloy piston of small sized ship during high speed driving (3000rpm) is analyzed the two-dimensional heat conduction problem using finite element method(FEM). Formulation of FEM based weighted residural method were presented for the analysis of the two dimentional axis symmetric conditions. And the pre and post-processor are composed for the easy decision of result and the exact analysis, and outcomes are plotted by using AutoCAD and AutoLISP. The consequence obtained in this study are summurrized as follows. In temperature distribution analysis, maximum temperature was shown in the centre of the crown, and the great temperature gradient was occurred on the wall of the piston.
