Abstract

In recent years, the application of impacts to precise positioning has been increased. Previously, the impulsive force or impact was generated by electromagnetic impulsive force or by the sudden deformation of a piezoelement. In this paper, a new actuator named as Air Impact Drive (AID) is introduced, in which the impact is generated by impulsive air pulse pressure. Free body diagrams and equations of this new actuator were drawn and determined. Experimental and theoretical results are in good agreement. The new actuator could displace a 0.2kg object at 0.1 of millimeter per pulse by pulse air pressure. By implementing suitable setup of parameters, the AID could move the object by continuous, constant air pressure with good linearity. This property is unique among other impact drives for positioning. By 0.3Mpa of source air pressure, the new actuator could move the mentioned object at the speed of approximately 13.4mm/s.
