The effect of ultrasonic friction reduction (UFR) has been found for a few decades and been applied in a series of fields, like mechanical design and manufacturing. Meanwhile it has also been successfully involved in pneumatic cylinders of pneumatic field. This research proposed an equivalent method for the seal-cylinder couple to be unfolded into a rubber bar-steel plate friction couple, in order...
Pneumatic piston-cylinder actuators are widely applied in industry for a variety of automation and robotics field. For suppressing leakage, these actuators incorporate seal rings which meanwhile introduce friction and affect the positioning precision and output force. The friction reduction by ultrasonic vibration has got wide and deep investigations by global researchers, and been successfully implemented...
