Helicopter control loading simulator having touch guidance

Abstract

The invention relates to a helicopter control loading simulator having touch guidance. The helicopter control loading simulator is characterized in that a table board base is composed of a lower bottom board of the table board base and a table board of the table board base, wherein the top surface of the lower bottom board of the table board base is fixedly connected with the table board of the table board base, a fixed base is fixedly connected to the top surface of the table board of the table board base, a transverse motion servo motor is fixedly connected with the table board of the table board base though the fixed base, a transverse motion plate-type reducer is arranged at the front end of the transverse motion servo motor, an outer lug of the transverse motion plate-type reducer is connected with the fixed base, a rotating bracket is of a right-angle-shaped structure, the bottom surface of the rotating bracket is fixedly connected with a flange face of the transverse motion plate-type reducer, and the helicopter control loading simulator can accurately provide touch guide force in real time according to a helicopter kinetic model and an operating lever model, so that the high-fidelity immediate force sense is simulated. Meanwhile, aiming at different helicopter types, the programming method can be adopted for simulating the small differences of the helicopter types in the aspect of force sense, and thus the helicopter control loading simulator has good adaptation and universality.

Description

Technical field [0001] The invention relates to a helicopter simulated manipulation load simulation device with tactile guidance, belonging to the field of robot human-computer interaction, and is a simulator manipulation load simulation device based on tactile guidance. Background technique [0002] In a real helicopter, the control load system is a direct device for the pilot to control the aircraft. Due to the complex flight environment of the helicopter, the flight status changes frequently. The flight parameters such as pitch angle, roll angle, rudder deflection angle and flight speed change rapidly. The aerodynamic force loaded on the joystick and pedal changes quickly. The pilot must rely on the control force. Changes quickly make judgments and execute corresponding actions. For the training of helicopter pilots, the safety and economic benefits of real machine training are very poor. Therefore, special simulation training equipment is needed to simulate the control of re...

AI Technical Summary

Problems solved by technology

However, due to its fixed form, the spring load cannot realistically simulate the dynamic force feeling in different flight states, and the hydraulic servo control load system is unstable in the subtle and slow operation due to hydraulic pipeline leakage, frictional resistance, etc. , these two control load systems are difficult to establish an accurate control load model, and the degree of simulation is far from the actual

[0005] In addition, the general helicopter simulator control load device does not consider the force interaction between the pilot and the device. The device feeds back the aerodynamic model force generated by the helicopter's flight state, but it cannot directly and quickly detect the pilot's judgment based on the joystick model force. manual operation force

This will easily lead to conflicts between the model force reflected on the joystick and the operating force of the pilot during the fast and frequent manipulation process, resulting in a sense of frustration. At the same time, the tactile guidance in the teaching mode cannot be realized, which in turn affects the sense of presence in the simulation training. and the final training effect
