Description

technical field [0001] The invention relates to the technical field of vibration testing of aero-engine structural parts, in particular to an aero-engine pipeline vibration testing device and method. Background technique [0002] With the mass production of aero-engines, the assembly quality of aero-engines is more and more considered to be the most important indicator to determine the final qualification and reliability of the engine. The overall assembly quality and rationality of the external pipeline of the engine are also an important factor in determining whether the aero-engine can operate effectively for a long time. Many scientific research institutes at home and abroad have carried out relevant research on the vibration test of aero-engine pipelines, but most of them are related tests after the pipeline assembly conditions have solidified. In the past, such tests had uncontrollable excitation sources and test conditions. Single and other limitations. [0003] The...
