| Abstract: | To resolve the problem of low reliability and frequent failures of the hydraulic system of part-face roadheaders,the reliability logic diagram and reliability calculation model of the system were established in accordance with the basic theory of reliability.Reliability calculation and analysis were conducted with a certain part-face roadheader made in China as an example,and the reliability simulation curves of each sub-system and the whole system were obtained via MATLAB,and measures for improving the system reliability were determined and presented. |
