Reliability analysis on arm frame structure of ship unloaders based on SFEM |
| |
Abstract: | By utilizing the SFEM combining the Monte Carlo probabilistic simulation method and finite element method,the paper studies the strength,rigidity and compressed bar's stability and reliability of the continuous ship unloader,and proposes a method which can comprehensively evaluate the system reliability of the continuous ship unloader structure.The case analysis shows that the method can guide the reliability design of the continuous ship unloader structure. |
