The Vibration Characteristics of Ultrasonic-Activated Straightening and Forming Machines

Abstract

The straightening and forming of metal parts are typical and usual tasks within shipbuilding industries. They may expose boilermakers to high levels of vibration, leading to potential health risks (musculoskeletal disorders and vascular syndromes). This study consisted of helping a company evaluate their hammering machines that were activated by ultrasound, comparing them to conventional impact tools. Vibration measurements were therefore carried out in the field. These were followed by an analysis of the signals according to the regulations and additional assessment tools.
