The numerical analysis is the basic step of machine designing and the result from it is the fundamental data for the assess management of machine/plant. Recently, many kinds of softwares based on different method, like Finite Element Method (FEM) and Transfer Matrix Method (TMM) were developed for the machine design. Especially the development of simulating a rotating component, gas/steam/wind turbine shaft, high speed shaft, the shaft of large vessels and the shaft with blades, flywheels and gears. In order to reduce the error, it always needs to increase the number of element, some times over 100,000. But it will affect the inputing matrix size and calculating time. In this paper, a 2D modelling method was proposed to reduce the element size and solving time. This paper compared the simulation results from MSC Partan/Nastran and ANSYS Workbench using a 3D model and the results by solving MATLAB based on FEM using a 2D model.
