In order to achieve high intensity, light quality, aesthetically pleasing these requirements, in the design of car wheel, not only have to choose the material that is light and fast, but also on its structure, the overall design layout, and the reasonable optimization design on the shape and size. Optimization design is a kind of to seek the optimal design scheme of technology, is one of the leading direction of mechanical product design and innovation and development, is an important means of production enterprises survival and development. With the development of science and technology, the analysis software of ABAQUS provides the optimization design and topology optimization of two optimization module is becoming more and more mature. Based on optimization design of automobile wheel hub based on ABAQUS environment is analyzed, so as to achieve high intensity, light quality, etc. Based on ABAQUS software, automobile wheel hub under normal load conditions are analyzed stress generated by the biggest parts of the thermal stress (area), and these parts for the reasonable design, makes every effort to the same constraints
