I would like to ask everyone: why is it required that the edge of the vibration-damping orifice plate in reciprocating machines be sharp? I asked the people in the moving equipment team, but they didn’t give a clear explanation; I’ll ask again here. The book says that the performance deteriorates after it gets dull (after chamfering), but why?

The article recommended at http://www.docin.com/p-889641859.html – after reading it, it seems to work on the same principle as flow orifice plates (applicable to this acute angle). It’s related to the angle of the eddy currents generated by the plate thickness, I guess. But it seems this device has certain limitations in terms of its range of application. Let’s see what the experts say; I’ll go get a stool :)
