The aim of this study is to investigate the performance and reliability of urethral valve driven by ultrasonic-vaporized steam.The performance model of urethral valve is established to analyze the driving and opening/closing performances of urethral valve.The reliability model of urethral valve is obtained,and the reliability simulation algorithm is proposed to calculate the reliability index of urethral valve.The 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. 展开更多
