Abstract

In order to accurately evaluate and predict workload of maintenance personnel, considering their ergonomic factors, such as force, posture and energy consumption, a workload evaluation model was established with the ratio of required time and resource to available time and resource as main evaluation value while energy consumption rate and ergonomic load as correction factors. Then, Simens JACK 8. 4 simulation software (JACK for short) was used to obtain required time and correction factors for the model, and an evaluation method based on this model and JACK was proposed. Finally, it was adopted to simulate and evaluate workload of A320 main wheel disassembly operation. The results show that this method can make up for deficiencies of existing workload evaluation methods of maintenance personnel, including their lack of practice, poor operability, strong subjectivity, and inaccurate prediction. It can easily and effectively evaluate and predict maintenance personnel's workload. © 2019 China Safety Science Journal. All rights reserved.
