Pilot workload-oriented cockpit panel layout optimization method

Abstract

The invention discloses a pilot workload-oriented cockpit panel layout optimization method. The method specifically comprises the following steps of determining a decision variable of a cockpit panel layout optimization model; establishing constraint conditions of the layout optimization model according to design requirements of a cockpit panel; obtaining pilot operation load scoring values corresponding to different panel layout positions in the virtual environment, and establishing a pilot operation load scoring function based on a BP neural network; and solving the cockpit panel layout optimization model based on a genetic algorithm, and determining the layout position of each control device on the cockpit panel. The design, research and development cost is reduced based on the digital prototype, meanwhile, the workload of the pilot is fully considered, and the method has important significance for reducing the operation load of the pilot and improving the flight safety.

Description

technical field [0001] The invention belongs to the field of aircraft cockpit layout design. Background technique [0002] The aircraft cockpit is the main activity place of the pilot and the human-computer interface for flight control, which is very important to ensure the safe flight of the aircraft. Reasonable and effective cockpit layout design plays a decisive role in ensuring that pilots complete flight tasks safely, efficiently and comfortably. Cockpit panel layout is a key indicator to evaluate the quality of cockpit design. A good cockpit layout can not only shorten the cockpit design cycle and reduce development costs, but also help improve pilot work efficiency, reduce operator fatigue, and improve flight safety. Therefore, facing the highly integrated aircraft cockpit, it is urgent to propose a reasonable aircraft cockpit panel layout design method. The current research methods for aircraft cockpit layout design have the following deficiencies: [0003] (1) Th...

AI Technical Summary

Problems solved by technology

[0003] (1) The design and evaluation of the cockpit layout cannot be realized in parallel, and the rationality of the design cannot be verified and analyzed by the pilots in time. Often, the rationality of the design is verified through simulated flight tests after the design is completed, which will inevitably lead to the extension of the design cycle. Increased costs

[0004] (2) The existing cockpit layout design method mainly combines flight procedures to design the layout of the panel by optimizing the control path and operation sequence, but does not consider the workload of the pilot during the operation, and does not optimize the operation load

[0005] (3) Simplify the control devices on the cockpit panel without subdividing the size and quantity of the devices, and the connection with the actual engineering is not clear enough to be practically applied to typical models
