Engine Parts Thermal Load Simulation Analysis

With the increasing of engine duty, engine parts', mainly the key parts of engine, thermal load analysis become more and more important in engine design and improvement process nowadays.The Finite Element Analysis (FEA) is a mainly method for engine thermal load analysis. This research is use the Finite Element Method (FEM) to simulate thermal load of engine parts.This paper is mainly about the structure design and thermal load FEA simulation of piston, cylinder bold and cylinder head at the stage of the beginning of one model engine design. This paper designed the structures of piston, cylinder bold and cylinder head according to some technique files. The design process is carry out in software Pro/E.This paper selects the boundary condition according to research data, formula and the target of future design. Meanwhile, the net and analysis process is carry out in ANSYS.The gas temperature and other factor's influence to piston thermal load have been analyzed in this paper. This paper also analyzed the inner cooling influence as the piston has high temperature load. Considering of the circumstance engine works in, this paper analyzed the thermal load of cylinder bold at some circumstance. Part of boundary condition influence also been considered. Base on the analysis result of cylinder head, new structure been designed. The boundary condition and structure's influence to both structure forms' thermal load have been analyzed also.Base on the analysis of these three parts' thermal load and influence factors, the thesis educed the base thermal load condition of each part and the mail influence boundary condition. The structure factor influence of cylinder head baseboard also been educed.
