摘　　要：为准确评估和预测机务维修人员工作负荷,结合机务人员的受力、姿势、能耗等工效学因素,首先以任务所需时间资源与可用时间资源之比为主评估量,以能量消耗率及工效学负荷为修正因子,建立机务维修工作负荷评估模型;其次应用工效学仿真软件Simens JACK 8. 4(简称JACK)仿真模拟得到模型中的工作所需时间和修正因子,并提出基于机务维修工作负荷评估模型和JACK仿真软件的机务人员工作负荷评估方法;最后用该方法仿真评估A320主轮拆卸作业工作负荷。研究表明:所提方法能够弥补现有民航机务人员工作负荷评估方法中存在的实验室化严重、操作性差、主观性强、预测困难等不足,可方便有效地评估及预测维修人员工作负荷。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.
