| Abstract: | The assessing of the health condition is the foundation of the safety and stable operation of the ultracentrifuge.This paper introduced the parameter of ultracentrifuge's health condition,and the common integrated assessment methods.Combining the reality of the ultracentrifuge,a comprehensive evaluation method based on artificial neural network and Dempster-Shafer evidence theory was proposed.By using Dempster-Shafer evidence theory,the method realized the fusion of artificial neural network outputs which w... |
