摘要：By attaching ultrasonic vibration to the electrode tool, the flow field will be improved and the debris concentration will be reduced by the pump suction effect and cavitation effect, thus the processing efficiency will be improved. The variation of pressure field, velocity field and particle distribution field in an ultrasonic vibration period is simulated by the element analysis software Fluent. The influence of ultrasonic vibration on pressure field, velocity field and particle distribution field is analyzed. The simulation results shows that the gradient of pressure distribution and the change of flow velocity are enhanced by the effect of ultrasonic vibration, which is beneficial to the excluding of machining debris, the reducing of arc discharge and short circuit, and the increasing of processing efficiency. ©, 2015, Editorial Board of Journal of Basic Science and Engineering.
