UNSPECIFIED (2009) Finite element analysis of an upper motorcycle piston. Faculty of Mechanical Engineering, Universiti Malaysia Pahang.



This dissertation describes the stress distribution of the upper piston with using finite element analysis. The finite element analysis is performed by using computer aided engineering (CAE) software. The main objectives of this project are to investigate and analyze the stress distribution of upper piston at the real engine condition during combustion process. The dissertation describes the mesh optimization with using finite element analysis technique to predict the higher stress and critical region on the component. The upper piston is implemented in the six stroke engine of 110 cc Modenas motorcycle. Aluminum 356-T7 is selected as an upper piston material. Despite all the stresses experience by the upper piston does not damage the upper piston due to high tensile strength but the upper piston may fail under fatigue loading. Thus, it is important to determine the critical area of concentrated stress for appropriate modification. With using computer aided design (CAD) which is SOLIDWORK, the structural model of an upper piston is developed. Furthermore, the finite element analysis performed with using MSC PATRAN and MSC NASTRAN. The finite element analysis is performed by using linear static stress method. The result of the analysis shows that mesh type of TET 10 give more accurate result compare to TET 4 at its each mesh convergence point. The stress analysis results are significant to improve the component design at the early developing stage. The result can also significantly reduce the cost and time to manufactured the component and the most important to satisfy customer needs.
