Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 Shown, a kind of flight simulator kinematic system modeling method based on Modelica shown in this embodiment comprises the following steps:

[0029] Step one, needs analysis.

[0030] According to the level, function and performance requirements of the flight simulator, analyze the various motion requirements of the flight simulator, and determine the various motion systems required by the flight simulator, such as the joystick control system, etc.

[0031] Step 2. Decomposition of the motion system.

[0032] Decompose the motion system obtained from the demand analysis, obtain the subsystems it contains, and then determine the components contained in each subsystem and the components contained in the components.

[0033] see figure 2 The schematic diagram of the system decomposition is shown. According to the anal...

Abstract

The invention discloses a Modelica-based flight simulator motion system modeling method. The method comprises the following steps: 1) demand analysis; 2) system decomposition; 3) designing a connector; 4) modeling a component layer; 5) modeling a part layer; (6) subsystem modeling; 7) system modeling; 8) modeling a control system; and 9) performing system simulation analysis and optimization design. According to the invention, modeling is carried out through a multi-field modeling language Modelica, so that a flight simulator motion system is prevented from using multiple pieces of software to carry out joint simulation during modeling simulation; the non-causal modeling mode can save the time of equation decoupling and programming when an engineer models, improves the simulation analysis efficiency of the flight simulator motion system, and provides an efficient design analysis method for the engineer.

Description

technical field [0001] The invention relates to the technical field of flight simulators, in particular to a Modelica-based flight simulator motion system modeling method. Background technique [0002] Flight simulators can simulate all or part of the aircraft's functions, performance, or certain types of systems, and provide trainees with special simulation training on complex systems such as technology, tactics, or weapon fire control and precision strike weapons. loop" real-time simulation system. [0003] Traditional pilot training is usually carried out with actual installations. This method is costly and difficult to coordinate, which will reduce the actual service life of the aircraft, thereby affecting the utilization rate and attendance rate of the aircraft. At the same time, there are safety risks in using actual installations for training. question. The use of flight simulators for pilot training can better solve the shortcomings of using actual aircraft for tra...
