Abstract
Accurate ergonomic risk assessment can provide favourable support for the improvement of workers' work tasks, and the traditional man-machine risk assessment method is inconvenient to operate, time-consuming and greatly affected by human subjective factors. In this paper, an ergonomic risk assessment system based on fuzzy theory is designed and developed, using the improved rapid whole body assessment (REBA) method based on fuzzy theory. The evaluation system uses a motion capture device to provide input and automate ergonomic evaluation, reducing time consumption. The reliability of the evaluation system was verified by the handling experiment, and the system evaluation results were compared and compared with the ergonomics expert and JACK software, and the results showed that the correlation coefficient between ergonomic experts and the system was r=0.947, and the correlation coefficient between JACK software and the system was r=0.856, which had significant correlation.
