Abstract

A three-degree-of-freedom aero-engine mounting posture-adjusting simulation system comprises a motion module, a posture-adjusting module and a force bearing module; the motion module comprises motionwheels and a chassis; the posture-adjusting module comprises a lifting-pitching device and a translation device; the lifting-pitching device comprises an upper connecting rod, a lower connecting rod,a transverse connecting rod and a hydraulic actuating cylinder; the translation device comprises a servo motor, a longitudinal lead screw, a transverse lead screw and a mobile platform; and the forcebearing module comprises a force bearing frame and an engine clamp. The three-degree-of-freedom aero-engine mounting posture-adjusting simulation system has the effects that lifting, pitching and translating are integrated in an engine mounting process and are further optimized, the posture of an aero-engine can be adjusted in an aero-engine mounting process, the structure is simple, the efficiency is high, the labor is saved, and human errors are reduced; through cooperation of the hydraulic actuating cylinder and the connecting rods, lifting and pitching actions in the aero-engine mounting process can be realized; and through cooperation of the servo motor and the lead screws, translational motion can be realized, and accurate control is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of aero-engine installation, in particular to a three-degree-of-freedom aero-engine installation attitude adjustment simulation system. Background technique [0002] At present, in the field of civil aviation in my country, the installation of the complete engine is still dominated by manual installation, and the research on digital installation of aero-engines is slow. However, the installation of the engine occupies a very important position in the process of aircraft assembly, and the quality of the installation directly affects the performance of the entire aircraft. Modern aircraft need to adopt the form of installation platform to shorten the disassembly and assembly time of the engine, improve maintenance efficiency, reduce human errors, and improve the maintainability of aircraft engines. [0003] With the advancement of science and technology, the engine installation platform plays a very important...
