Fuzzy Reliability-Based Optimal Design for the Primary Cylinder of Giant Hydraulic Forging Press
300MN forging hydraulic press is the essential equipment in our country national defense and the infrastructure, and the primary work cylinder is one important part of the hydraulic press. In view of the judgment on the Working States of the primary work cylinder whether safe existence fuzziness, which has carried on the fuzzy reliability analysis and computation to the primary work cylinder probability law design result and the method of safety coefficient design result, the computed result indicated that, the design result with traditional safety coefficient is conservative, but based on probability design result is not safe enough. At the same time, under the condition that don’t reduce the fuzzy reliability, which has carried on the optimal design based on the finite element software to the thickness of the primary work cylinder.
