State Machine Logic Vibration Control Simulation of Rotary Impact Driver

Rotary-impact mechanisms generated high-impulse torques directly to the screws with relatively low input power. However, this type of tool also generates noise and vibration that may affect the operator who uses it. This paper develops a supervisory logic control based on a state-flow control algorithm on the model to improve the shortfalls. Testing and evaluation are made through experiment and optimization through simulation. The results showed a 19% vibration reduction from the motor’s reaction torque to the user’s arms. The outcome may improve the user’s comfort, reducing the cause of hand-arm vibration and increasing the workers’ allowable work time.
