Abstract

In order to improve the safety level of assembly line work and solve the fatigue hazard of workers in assembly line work, the influencing factors of fatigue were analyzed with fault tree analysis (FTA) method, and the fatigue safety resilience model of workers was constructed. The model consisted of three modules: management system, fatigue repair and man-machine system. The model runs continuously in four stages of resistance, recovery, learning and optimization. Based on the practical application of the model, the fatigue management redundancy system was constructed, and the approximate and accurate rest mechanism and the conveyor belt alarm system were proposed. The results show that the fatigue management redundancy system has the function of monitoring and feedback information, and can prevent the fatigue damage of the factory. The fatigue repair method can approximately or accurately determine the rest time, and can avoid fatigue in the same posture. Optimizing human-machine systems can improve human factors reliability and environment. The model can eliminate the hazards of long-term work in the same-position, reduce fatigue and effectively solve the fatigue risk of the factories. © 2020 China Safety Science Journal.
