Comprehensive evaluation and analysis of design scheme of automatic feeding and discharging device for freeze-drying system

Abstract

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.
