| Abstract: | Reliability is one of the important performance index of the fluid driven rotary milling head.Fault tree analysis(FTA) can help the designer to find the problem and defect.It is meaningful to improve the design and increase the reliability by the analysis.The reliability model of the swing table for milling was established.Depend on the FTA,the weaknesses of the system were found out.The effective methods were presented to improve the reliability of the system. |
