【 摘 要 】

The reliability of the aseptic feeder in small-scale production is unstable. This paper proposes a triangular fuzzy evaluation method, which can derive the probability of occurrence of basic events in the FTA model. Sensitivity analysis is used to identify the largest source of risk for a fault and is verified by ANSYS simulation. Studies have shown that the reliability of a sterile docking instrument is 72.98%.Considering that the instrument is still in the research and development stage, it is necessary to further optimize the temperature field of the heating piece to provide construction for the reliability growth of the aseptic feeder instrument.
