【Abstract】 From the system point of view, a twostage amplification of ultrasonic vibration cutting systemwith non-clamped symmetrical connecting vibrator wasstudied theoretically and experimentally under differentload conditions. The influence of system structure parameters and load conditions on two-stage amplificationwas proposed, which would be useful for the design ofultrasonic vibration cutting system.更多还原
