Finite Element Analysis of Low Speed and Heavy Load Gear

Abstract With the development of computer technology and the development of the science and technology, the finite element analysis software ANSYS in mathematical analysis, mechanical analysis and engineering analysis is an integrated structure, thermal, fluid, acoustics and other disciplines of a very effective universal finite element analysis software。 Using ANSYS finite element analysis is carried out on the parts, can be quickly and easily analyze the mechanical parts of the stress, strain, deformation, fatigue analysis of such a variety of components, and can be simulation of a variety of more complex systems, and also can realize the virtual design and simulation, through the analysis of this kind of software greatly saves the design of the human, financial and material Resources。 Due to the use of the software analysis of convenience, practical and effective, in every field, ANSYS finite element analysis software, especially has been engineers is widely recognized and applied in the field of mechanical engineering research and development。

Tooth profile curved surface is an involute surface, so for the  modeling difficulties and key, in how to determine the precise involute。 By using in  3D Modeling Software Solidworks equations driving curves to create a standard spur gear, learning and using ANSYS software to create good planetary gear model  were accurate mesh, and static loading and analysis and solution of the model, to solve the check, analysis and optimization。

Key words: ANSYS Finite element analysis Involute Gear SolidWorks
