| Abstract: | For the failing to move up and down of the hydraulic cylinder in the hydraulic balance loop experi- ment, fault tree is an effective analysis method to find out the crucial reason by accelerating the speed of fault diag- nosis. Using the non - action status of hydraulic cylinder as the target, the method decomposes the fault and then figures out the whole factor as well as subordinate ones. By analyzing and ruling out each factor, we finally get the problem solved and create an ideal condition for the hydraulic cylinder. |
