| Summary: | 碩士 === 朝陽科技大學 === 工業工程與管理系碩士班 === 96 === Manual materials handling (MMH) is one of the most common activities in industries. Ergonomics-related factors such as over exertion, awkward posture, and repetitiveness may increase the joint moment on L5/S1 and result in low back pain. In this study, an experiment was conducted to collect the parameters of kinetics and kinematics in the laboratory where motion analysis system and force platform were executed. The experimental motion data was used as an input to Adams_LifeMOD software to construct a simulation human model for lifting tasks. The inverse dynamics and forward dynamics were calculated in the software to obtain the simulated joint forces of the human body. The human and environmental parameters (such as motion agent, bushing and gain) were adjusted in Adams_LifeMOD in order to meet the model criterion that the error percentages between the simulated and experimental ground reaction forces (and joint forces of human body) were within the acceptable error range (±25%). The simulation human model was then constructed and used to evaluate the joint forces of human limb while the heavy object load (40kg and 60kg) is not allowed to be lifted due to the consideration of possible injury.
