Aircraft steering wheel force feedback system

Abstract

The invention discloses an aircraft steering wheel force feedback system for simulating the drag force sensed by both hands of a pilot in aircraft flight, belonging to the field of force sense interactive devices. The system has two degrees of freedom, i.e. the left and right rotation of a steering wheel and the front and back movement of a control lever. The rolling and the pitching of an aircraft are respectively controlled in a virtual environment, and the movements in the two degrees of freedom are not coupled. The device mainly comprises a steering wheel, a control lever, two coders, four reels, four steel wire ropes, four tension springs, four transmission shafts, two AC servo motors, two speed reducers and a pedestal. When the steering wheel is rotated or the control lever is pushed and pulled by hands, the corresponding coder acquires the position signal of the steering wheel or the control lever, an upper computer calculates the shaft angle of the corresponding motor in real time, the motor is controlled to carry out position servo to drive the steel wire rope to drag the spring to complete certain deformation, and the force moment produced by the spring deformation is transferred to the steering wheel or the control level so that people can sense feedback force. The invention has the advantages of reliable operation and high precision, and meanwhile, the magnitude ofthe feedback force can be freely adjusted according to user demands; and the system can be applied to pilot flight training and other types of aircraft simulated flights.

Description

technical field [0001] The invention relates to an aircraft steering wheel force feedback system, which simulates the resistance felt by the pilot's hands during aircraft driving, is a two-degree-of-freedom force-sense interaction device, and belongs to the field of human-computer interaction devices. Background technique [0002] Virtual reality (Virtual Reality, VR) is based on computer technology as the core, combined with related science and technology, to generate a digital environment that is highly similar to the real environment in terms of sight, hearing, touch, etc. within a certain range. Objects interact and influence each other, which can produce feelings and experiences equivalent to the real environment. [0003] It is an important development direction of virtual reality technology for operation simulation and skill training. In recent years, virtual reality simulation training system has been widely used in various fields of industrial design, military, medi...

AI Technical Summary

Problems solved by technology

[0006] In recent years, due to the development of the aviation industry at home and abroad, the demand for aircraft flight training simulators for training pilots has increased greatly. At present, the aircraft flight training simulator products for civil aircraft in China are all dependent on imports, which are mainly monopolized by foreign companies. Imported aircraft simulator technology is restricted by foreign manufacturers, and the price is extremely expensive, especially after-sales service and spare parts.
