| Abstract: | In the process of fault diagnosis on hydraulic systems, various fault causes are interacted leading to the fuzziness of equipment faults. However, the traditional diagnosis methods are conducted based on expertise and easy of diagnosis errors. In this study, the hydraulic system of a specific forklift is used as an example. By employing the synthesized fuzzy evaluation method, such advantages as simplicity, error-tolerance and intelligent-analysis can be attained. Therein, the reliability and efficiency of the proposed method are proven. |
