Abstract

Exoskeletons can be used in workplaces where vibrating power tools are applied. The influence of these support systems on vibration exposure and impact remains unclear. In an experimental laboratory study, the influence of two passive exoskeletons for the upper body when working with a drill was compared to a task without exoskeletons. Vibration exposure, transmissibility to the wrist, feed force, muscle activity, muscle fatigue, posture and vibration perception thresholds were measured on 30 subjects. Vibration exposure at the machine handle was higher with both exoskeletons than without an exoskeleton. The vibration perception threshold at 125 Hz shifted less after using the exoskeletons than without using the exoskeletons. When wearing exoskeletons with a strong support torque, increased vibration exposure and higher abduction of the upper arm may occur. The results indicate that exoskeletons reduce the transmission of vibrations in the lower frequency range.

外骨骼钻孔：手臂振动对神经和肌肉结果的影响。

外骨骼可用于使用振动电动工具的工作场所。这些支撑系统对振动暴露和冲击的影响尚不清楚。在一项实验实验室研究中，将两个被动式外骨骼在使用钻头时对上半身的影响与没有外骨骼的任务进行了比较。测量了30名受试者的振动暴露、手腕传导率、进给力、肌肉活动、肌肉疲劳、姿势和振动感知阈值。有外骨骼的机器手柄处的振动暴露比没有外骨骼的要高。使用外骨骼后，125 Hz的振动感知阈值比不使用外骨骼时位移更小。当佩戴具有强大支撑扭矩的外骨骼时，可能会增加振动暴露和上臂的高度外展。结果表明，外骨骼减少了低频振动的传播。

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.
