Abstract

The invention relates to an aircraft landing gear simulator which comprises a signal simulation unit for receiving manipulating instructions of a landing gear and a processing unit. The processing unit is coupled with the signal simulation unit, uses the manipulating instructions of the landing gear as the input of an operated aircraft landing gear real-time model, and outputs at least one state parameter to the signal simulation unit and a display unit. The processing unit comprises at least one instrument coupled to the signal simulation unit, wherein the at least one instrument correspondingly displays at least one state parameter, and the aircraft landing gear real-time model comprises a hydraulic mechanical system module and a control system model. The aircraft landing gear simulator does not require any testing member of real physical tests and can finish various parameter testing and analysis of a landing gear collecting and releasing system. Additionally, partial real parts are replaced under the laboratory environment for performing testing, so that testing times and strength can be reduced, testing cost can be saved, and safety of personnel in dangerous testing is ensured.

Description

technical field [0001] The present invention relates to an aircraft landing gear simulator, in particular, to a semi-physical and real-time aircraft landing gear simulator that unifies the modeling of the mechanical system part, the control system part and the hydraulic transmission part of the aircraft landing gear and realizes hardware-in-the-loop. Fall simulator. Background technique [0002] The aircraft landing gear retractable system is an important executive part of the aircraft, which is used to realize normal landing and support the aircraft on the ground when the aircraft lands. The reliability requirement of this device is very high, and involves many fields such as machinery, control and hydraulic pressure. [0003] At present, simulation software digital off-line simulation calculation is mainly used in the design process of aircraft landing gear retraction system. On the one hand, in this kind of simulation simulation, only the simulation of the static input a...
