A five-degree-of-freedom continuous load simulator overload simulation control method

Abstract

The present invention relates to the technical field of flight simulators. The purpose is to provide a five-degree-of-freedom continuous load simulator overload simulation control method. The present invention includes obtaining the operation instructions in the flight operating system on the five-degree-of-freedom simulator cockpit and entering the simulation model; Through the actual flight of the aircraft in the simulation model, the motion parameters of several degrees of freedom, the angular velocity and angular acceleration of the boom around the main axis are obtained, and then according to the yaw angle movement of the actual flight, the rotation angle of the yaw axis is obtained, and the actual flight relative The acceleration component of the pitch frame coordinate system and the rotation angle of the roll axis; judge the motion state of the vertical motion frame, and obtain the rotation angle of the pitch axis in pure overload; the rotation angular velocity and rotation angular acceleration of the main shaft, the rotation angle of the roll axis, and the pitch axis The rotation angle of the yaw axis, the rotation angle of the yaw axis, and the acceleration of the vertical motion box are sent to the continuous load simulator.

Description

technical field [0001] The invention relates to the field of flight simulators, in particular to an overload simulation control method for a five-degree-of-freedom continuous load simulator. Background technique [0002] With the development of computer and simulation technology, more and more attention has been paid to flight simulation training, which has become an effective way to improve pilots' flying skills, ensure training safety, shorten training cycle and save training cost. The flight simulation training device is a device that simulates the flight state, flight environment and flight conditions of the aircraft when it performs a flight mission, and provides the pilot with similar control load, vision, hearing, and kinematic sensations. The kinematic sensation is provided by the motion platform of the training device. [0003] With the development of high-performance fighter jets, pilots will be subjected to continuous high G value acceleration. For example, the ma...

[0006] The four-degree-of-freedom continuous load simulator can realize accurate simulation of overload. Compared with the four-degree-of-freedom continuous load simulator, the five-degree-of-freedom continuous load simulator adds a vertical motion frame, thereby increasing the control of the vertical degree of freedom. At present, there is no sufficient Overload simulation control method using vertical degree of freedom
