Real-time fault detection in bolted assemblies using torque-angle signatures

Author

Abstract

"Deviation in the shape of a torque-angle signature can be an indication of a fault in a bolted assembly. The object of this thesis is to develop a methodology that can analyze the torque-angle signature generated after using a sensor-embedded rotary tool, where the torque-angle data is transferred to a computer, and determine in real-time if the assembly process has been successful or not. The methodology relies on the torque and angle values of the four transition points between the four zones on the torque-angle signature. The experiments conducted on ideally "perfect" assemblies show considerable variation on the angle component of transition points, while variation on torque is relatively small for such ideal cases"--Abstract, page iii.
