Modelica-based flight simulator motion system modeling method

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...

Problems solved by technology

[0005] The simulation of the simulator motion system usually requires coupling simulation of the mechanical-electrical-hydraulic system, and usually requires multiple design simulation software for joint simulation, and the causal modeling method adopted requires engineers to spend a lot of time on the decoupling of the equations, and for Different solution needs need to establish different simulation models (such as the kinematics forward solution and inverse solution of the six-degree-of-freedom motion platform), which will cause engineers to waste a lot of time on the establishment of the simulation model of the simulator motion system
