主　　题：Urethral valve ultrasonic opening/closing performance driving performance reliability 

摘      要：The aim of this study is to investigate the performance and reliability of urethral valve driven by ultrasonic-vaporized *** performance model of urethral valve is established to analyze the driving and opening/closing performances of urethral *** reliability model of urethral valve is obtained,and the reliability simulation algorithm is proposed to calculate the reliability index of urethral *** numerical simulation and experimental results show that urethral valve has a good opening/closing performance,the driving performance can be improved by increasing ultrasonic intensity,radiation area and ultrasonic frequency,and the corrosion and aging of driving bags are the weak links of urethral valve.
