Real-time simulation system of large aircraft hydraulic system

Abstract

The invention belongs to the technical field of design of airborne hydraulic systems and relates to a real-time simulation system of a large aircraft hydraulic system. The real-time simulation system of the large aircraft hydraulic system comprises a human-computer interface interaction subsystem and a real-time calculating subsystem which are connected through the real-time Ethernet. The real-time simulation system of the large aircraft hydraulic system is based on the advanced design ideas such as distributed type parallel simulation and system integrated modeling, rapidly achieves rapid prototyping of a control system, aims to build a multi-system integrated digital model, tries to comprehensively reflect the complex integration and coupling among multidisciplinary subsystems such as a mechanical subsystem, a hydraulic subsystem, an electrical subsystem, an electronic subsystem and a control subsystem, and sees through and obtains more qualities of the large aircraft hydraulic system clearly.

Description

technical field [0001] The invention belongs to the technical field of aviation airborne hydraulic system design and relates to a real-time simulation system for the aircraft hydraulic system. Background technique [0002] At present, the design of my country's airborne hydraulic system is still in the traditional design-verification-design improvement-verification process. A large number of verifications need to be verified through the iron bird physical platform. The main problems are as follows: [0003] 1) Due to the lack of technical means and design methods at the early stage of design, the rationality and correctness of system design cannot be guaranteed, and various parameters cannot be matched with other related systems, and design defects cannot be quickly verified and improved; [0004] 2) In the design verification stage, various physical tests such as "iron bird test" are used to conduct system integration and overall machine performance verification. On the one...

Problems solved by technology

[0003] 1) Due to the lack of technical means and design methods at the early stage of design, the rationality and correctness of system design cannot be guaranteed, and various parameters cannot be matched with other related systems, and design defects cannot be quickly verified and improved;

[0004] 2) In the design verification stage, various physical tests such as "iron bird test" are used to conduct system integration and overall machine performance verification. On the one hand, the cost is high; It is necessary to investigate and modify the design plan, or even overturn the original plan, causing more repetitive work;

Therefore, the construction mode of the real-time simulation system adopted by this patent cannot well solve the demand for real-time simulation of complex redundant aircraft hydraulic systems
