Abstract

In order to investigate the hand-borne vibration transfer characteristics of overhead slap picking operations, reduce the hand-borne vibration hazards of slap picking operators and prevent the occurrence of hand-arm vibration diseases, this study took overhead slap picking operators as the research object, set up the mechanics model of the upper limb of the picking operation, carried out experimental research on the picking rod modes, and analyzed the hand-borne vibration characteristics of the picking operators. It was found that the overhead slap picking operator has a higher risk of triggering hand-arm vibration disease. The axial vibration of the operating rod is much larger than the tangential and radial vibration, which is the main factor triggering hand-transmitted vibration; the radial vibration from the back of the hand through the wrist to the small arm is absorbed in large quantities, and the tangential vibration from the small arm through the elbow joint to the large arm is absorbed in large quantities. In addition, the difference in the body size of the aerial beat picking operator also leads to the difference in the transmission of vibration from the back of the hand to the small arm. Therefore, not only the radial protection of the wrist but also the tangential protection of the elbow joint should be strengthened for overhead slap pickers. The results of this research can not only provide a reference basis for the optimization of the tapping mechanism, handle and carrying device, but also provide an important reference for the early diagnosis and protection of hand-arm vibration disease.
