Abstract

Safety plays a key role in ensuring the efficiency of demolition operation. Exploring the fatigue development of demolition operators in the operation process at the view of safe man-machine and risk control is not only conducive to improving the safety and humanization of operation design, but also in favor of ensuring the physical and mental health of operators. This research aimed to explore the law of development and influencing factors of demolishing task that are contribute to prevent WMSDs and design assignment for demolishing task. A simulated demolishing task was designed and 10 male college students were recruited as participants. Then the pushing and griping strength before and after demolishing and MET, were measured, and the RPE for four limbs and waist after demolishing were collected to explore the influence of the size of demolition equipment, demolishing height on fatigue for demolishing task. In addition OWAS was employed to analyze poor working postures and evaluate the risk on demolishing task. The results show that the decrease degree of pushing strength was significantly greater than that of griping strength, and the risk of fatigue accumulation was greater. The size of the demolition equipment did not affect the development of human fatigue in the process of demolition operation. Furthermore demolishing height had a great impact on MET, which would affect the accumulation of fatigue. The posture risk shows that the posture risk of 115cm is lower than 65cm, but it also needs to be corrected as soon as possible.
