On the Design and Realization of an Information System for College Examination Management on Basis of Multi-layer Calculation Model

According to siphonic bedpan´s work principle, siphonic bedpan with variational section flow channel is put forwards into application in this paper. Structure design optimization of siphonic bedpan´s flow channel is discussed. Based on making use of Pro/E to conduct the parametrization modeling of the siphonic bedpan (the constant section bedpan and the variational section bedpan), and then adopt ADINA to simulate the flow field in the siphonic bedpan with not taking the filth into consideration. The calculation results of the numerical simulation demonstrate that variational section bedpan is better than the constant section bedpan in flushing and saving water. The results indicates the adoption of ADINA software to carry out sanitary implement´s numerical simulation can improve the accuracy of the bedpan design and manufacturing consumedly, provides a theories analysis foundation for the engineering, design and application of bedpan.
