Reliability analysis of certain aircraft's hydraulic pipe

Based on software Ansys, the stress distribution of hydraulic pipe wall can be obtained by finite element analysis. The maximum von Mises stress on certain type of aircraft's hydraulic pipe wall which is easily extracted from the results of POST1 is taken as random output variable, and hydraulic pipe sizes and material properties are regarded as random input variables. Then the reliability and sensitivity of maximum von Mises stress in the model can be analyzed and studied when mathematical models of a hydraulic pipe reliability analysis is established.
