Abstract
When holding or carrying vibrating machines, the coupling forces play a major role in transmitting the vibrations to the hand-arm system. In an epidemiologic study, two recommended methods from ISO/TS 15230-2 are used to investigate the relationship between coupling force-adjusted vibration exposures and their related risk of musculoskeletal disorders of the upper limb. Therefore, coupling forces have been professionally estimated for 408 machines used by 683 male participants during their entire working life and coupling force-adjusted long-term vibration doses are calculated. Despite different approaches of the two methods, overall lower dose values are correlated to the risk of musculoskeletal disorders if the coupling force was adjusted. Considering the 10% increased risk of musculoskeletal disorders, the original cumulative vibration doses of 19571 m2/s4 fell to 15995 m2/s4 and 18119 m2/s4 according to two different coupling force-adjusted doses. These results show the necessity of consideration of coupling forces, especially for on-body measurements.
期刊介绍:
Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives.
The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people.
All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
