Reliability analysis of marine oil hose fatigue testing machine

摘要

The reliability analysis is one of the most important procedures in the design of the oil hose fatigue testing machine. In this study, the reliability of fatigue testing machine was calculated using the finite element and probability method. In this process, the most dangerous point was confirmed using static analysis and transient analysis of finite element, the equivalent stress mean and standard deviation were worked out by radius vector method, the reliability of fatigue testing machine was calculated by probability method. The results showed, this fatigue testing machine can meet the safety and reliability requirements.
