A vibration control for disassembly of turbine blades

Abstract:

Typically, disassembly forces are unknown due to high forces or high temperatures during product operation, where assembly connections solidify. For the regulation of disassembly forces a controller is developed. The controller is formed for two steps: The first step is a PID controller that produces a force, which overcomes a solidifying force slightly. The second step is a vibration controller with a FM modulation to regulate the frequency of impacts. Vibrations are useful for decreasing the force amplitude for caring the joined components. Finally, the control is validated with disturbances in a simulation.
