Therefore, it is of great significance to evaluate and verify the maintainability of aeronautical equipment. The virtual maintenance task simulation method and ergonomics evaluation method are studied. The man-machine ergonomic evaluation of virtual maintenance simulation process is carried out, and a suggestion report is presented for the design process of virtual maintenance task. It is of great significance to verify the maintainability of civil aircraft engine. Firstly, the architecture of virtual maintenance system is analyzed, and the prediction method of virtual maintenance time is studied. The process from the establishment of virtual maintenance object to the creation of virtual human model and then to the creation of virtual simulation environment is expounded. In the simulation process of virtual maintenance task, using model method and virtual simulation platform, the virtual maintenance time of maintenance task is accurately predicted, and the accuracy of virtual simulation is improved. Secondly, the principle of ergonomics evaluation is studied, and the method of ergonomics evaluation is put forward. The JACK analysis module is studied, and the static strength evaluation method, energy loss evaluation method, fast upper limb evaluation method, fatigue and recovery analysis method are proposed. The simulation process of virtual maintenance task is evaluated by ergonomics, and the visibility and accessibility are obtained. Comfort, fatigue recovery time, and energy consumption. Finally, based on the comprehensive evaluation method of fuzzy theory, the maintainability index system of civil aircraft is established to realize the comprehensive evaluation of civil aircraft maintainability. The virtual evaluation results are obtained by JACK, and the maintainability of civil aircraft products is evaluated comprehensively by using fuzzy theory comprehensive evaluation method. Finally, the maintainability verification is realized.
