| Abstract: | There are many factors to influence the critical press of the hydraulic cylinder.The action mechanism is not entirely clear about how various parts of the hydraulic cylinder work on its stability, moreover,the load of the hydraulic cylinder is fuzzy and random.In the paper,the fuzzy reliability of the hydraulic cylinder stability is calculated according to mechanical fuzzy reliability theory,which provides an important reference for the design of the hydraulic cylinder.In addition,linear membership function... |
