Abstract: The application of computer in material science and engineering is developing increasingly. To use the technology correlatively, for example, data processing, simulation techniques, mathematical model and database etc. Through the process of establishing the mechanism model, using a computer data analysis process in materials science, the model predicts the optimal design to achieve. Computer application technology continues to evolve, gradually and comprehensively solve the major technical problems in materials science and engineering. The paper analyzed the substances of computer application in the materials science and engineering, optimization, curve and fitting expression and crystal growth.

Abstract: In the paper，intrinsic mode of parts clutch were analysised to get their proper frequency. Some parts of the cluch were made the whole flow of the topological optimization， and were carried on to re-design on this foundation providing the reference for the later design.

Abstract: This paper researched combining K-Means algorithm with method of spatial index in spatial database, and analyzed mainly research results of spatial index technology based on K-Means algorithm and their technical scheme. Finally, research trend of combining clustering and spatial index was proposed.

Abstract: Based on the explicit dynamic finite element analysis software, the use of hybrid cellular automata (HCA) as an optimization model, the collision of beams in the aluminum front structure optimization design. The 6061 aluminum alloy before the collision of beams to replace a model of the original steel beams, trolley collision simulation and experimental validation of the results show that the aluminum front impact beams than the original steel before the collision beam quality to reduce by 25% and has a higher flexural strength, low-speed collision, aluminum front impact beams than the original steel system energy absorption increased by 45.6%.
