In order to protect the products in the circulation process, cushioning packaging materials are used for the general packaging design, that is, to determine the process of circulation of products, product features and the vibration transmission characteristics of package materials and so on. This test system obtains the vibration transmission curves by the test of vibration transmission characteristics of packaging materials. This provides a reliable data basis for anti-vibration design so that the properties of cushioning materials can be played well and protects the products while reducing packaging cost, thus products can be competitive in a good position in the markets.

In order to improve the reliability of the design scheme, objective design scheme evaluation methods were selected to the optimal scheme. According to the existing problems of the automatic feeding and discharging device prototype for the freeze-drying system, operator’s actions which included disassembling and cleaning the device were simulated by the software of Siemens Tecnomatix Jack. The analysis results were verified and guided the design direction. Analytic hierarchy process, grey correlation analysis method, and combination of the above two methods were applied. Design scheme was determined according to the evaluation results. The results obtained schemes, design evaluation. According to the evaluation results, the first scheme was selected. It can be seen that gray correlation analysis is applied, and more objective manner is used to provide a reference.

In order to solve critical process parameters characterize aluminum grating is proposed to optimize the impact of stress calculation values are based on a nano-indentation experiment-Method strain relationship parameters. By establishing numerical approximation model to fit the experimental data of training, and the experimental data for numerical optimization. Experimental results show that: the method to calculate the yield strength aluminum material property parameters, namely strain hardening exponent, and obtained more satisfactory aluminum material properties parameter elastic modulus and yield strength relationship by comparing the value of the deviation can be found in the obvious effectiveness of this approach, but also proved a reliable orthogonal experiment. The research process parameters characterize the relationship between the aluminum grating characterization and constitutive model provides a reference and basis for, and also provide a basis for the development of intelligent raster scored.
