抄録
The accelerated fatigue testers, which involve compliant structures in the pipe wall near the tested valve, was developed. And effect of the compliance on pitting of a leaflet was evaluated. As a preliminary test, duralumin disks were used. Tests run in 600 cycles/min. for 15h. In all cases, few pits were observed on the outflow side surface of disks but a lot of pits on the inflow side of those. The number, size and depth of pits were clearly (more than twice in many areas) increased by the existence of the wall compliance. It is suggested a compliance could cause severe cavitation erosion. Compliant structure must be account for design of accelerated fatigue tester from the view of cavitation erosion. Keywords: Artificial heart valve, Cavitation erosion, Accelerated fatigue tester, Compliant structure
