Abstract
A pneumatic impact wrench is a hand-held tool used to secure screw type fasteners onto machinery. The impact mechanism, contained within the wrench, transforms the torque from the tool's air motor into radial impact pulses that tighten or loosen fasteners. The design variables of the mechanism that affect the output torque delivered to the fastener are not well understood. The current method of analyzing an impact mechanism involves fabricating and testing a series of physical prototypes. This is time consuming and costly due to the complicated geometry of the mechanism parts and the many unknown factors that affect the output torque. This thesis will demonstrate that an impact mechanism can be accurately simulated using a commercial dynamic mechanism analysis software program. From this computer model, several variables can be analyzed to determine their effect on the output torque of the total mechanism system.
