Research on stress load of joints in handling the work based on ergonomics

When human being is handling the work, it is obvious that the posture of work and the complexity of the force structure. During the work, the position of hands and the posture of the body, which not only relate to the efficiency of work but also the health of the body. The forces are studied in the case of the human handle the work according to the perspective of human engineering principles, analyze the force on our wrist, knee and ankle in different situations based on the working posture. According to the research and analysis to form mechanical load data in handling the work for each joint. Which not only relate to the efficiency of handling the work, but also ensure the safety of each joint in handling the work for human being.
