Push/Pull任务中肌肉疲劳评估的新方法
A new approach to muscle fatigue evaluation for Push/Pull task
摘要：
推/拉任务是许多行业工作的重要组成部分。通常，大多数研究人员通过分析不同的姿势条件，力的要求，速度因素等来研究推/拉任务，但很少有研究报道疲劳的影响。由物理负荷引起的疲劳是导致肌肉骨骼障碍（MSD）的主要原因之一。本文考虑关节肌肉群，从关节水平提出了一种新的手臂推/拉操作肌肉疲劳评估方法。这项工作的目的是预测肌肉疲劳的情况下，在推/拉任务，以减少MSD问题的工人的概率。一个案例研究，使用这种新的方法来分析推/拉手臂疲劳。
英文摘要：
Pushing/Pulling tasks is an important part of work in many industries. Usually, most researchers study the Push/Pull tasks by analyzing different posture conditions, force requirements, velocity factors, etc. However few studies have reported the effects of fatigue. Fatigue caused by physical loading is one of the main reasons responsible for MusculoSkeletal Disorders (MSD). In this paper, muscle groups of articulation is considered and from joint level a new approach is proposed for muscle fatigue evaluation in the arms Push/Pull operations. The objective of this work is to predict the muscle fatigue situation in the Push/Pull tasks in order to reduce the probability of MSD problems for workers. A case study is presented to use this new approach for analyzing arm fatigue in Pushing/Pulling.
