Abstract

The invention discloses a vibration performance simulation test device of a lubricating oil tank-mounting structure, and belongs to the technical field of aero-engines. The device comprises a casing base, a simplified lubricating oil tank and a mounting structure assembly. According to the method, feature extraction is carried out on the actual engine model, the actual model is simplified, the model is highly similar to the actual engine, and kinematics and dynamics characteristics of a system composed of parts such as an actual engine case, an installation structure assembly and a lubricating oil tank are restored to a great extent. The device and the method face dynamic design and vibration analysis and evaluation of a space multi-point supporting system, and are used for researching system vibration performance of a lubricating oil tank-mounting structure system under different supporting conditions and vibration transmission performance of a mounting structure.

Description

technical field [0001] The invention belongs to the technical field of aero-engines, and relates to a vibration performance simulation test device of a lubricating oil tank-mounting structure. Background technique [0002] The lubricating oil tank is an important component of the external system of the aero-engine. It mainly plays the role of loading lubricating oil. The lubricating oil tank is fixed on the engine casing through the installation structure. During the operation of the engine, the vibration generated by the casing will be transmitted to the various parts of the installation structure and the lubricating oil tank components. The lubricating oil tank has a large mass after carrying the lubricating oil, and the lubricating oil sloshes during the flight of the aircraft, making it difficult to control the vibration of the lubricating oil tank. The requirements for the strength and rigidity of the various parts of the installation structure and the lubricating oil t...
