A modular multifunctional rotor test bench

Abstract

The invention provides a modularization multifunctional rotor experiment table. The experiment table comprises an experiment table main substrate, a rotation roulette stress test module, a rotor dynamic balancing and rotor vibration characteristic experiment module, a rotor system fault simulation module, a crack rotor and square shaft rotor vibration parameter experiment module, a non-synchronous support rotor module and a hydrops rotor module. Each module consists of a corresponding module substrate, a rotation shaft, a roulette and a bearing, equipped with a displacement and speed measurement sensor and connected with a data acquisition system and a PC. Each experiment module retains an installation positioning port of the experiment table main substrate towards the outside, and is achieved through a flexible coupling. According to the invention, the experiment table is high universal and interchangeable; the experiment device is convenient to install and disassemble; the rotor system on the experiment table can be timely improved; and the experiment table has multiple functions, is capable of simulating multiple states of rotor operation and can be applied to the field of teaching experiments or scientific research of rotor dynamics and fault diagnosis.

Description

technical field [0001] The invention relates to an experimental device, especially capable of simulating the rotation of engine blades, completing the dynamic balance of the rotor, extracting and analyzing the vibration characteristics of the rotor shaft system when failures such as friction, misalignment, and cracks occur, and observing and verifying the asymmetrical support and A modular rotor test bench with multiple functions such as the influence of effusion on the critical speed of the rotor. Background technique [0002] Rotating machines such as aero engines are widely used mechanical devices in industry. The blades of the engine will elongate due to the action of centrifugal force during rotation, which will reduce the gap between the top of the blade and the casing, which will affect the efficiency of the engine and cause accidents due to collisions. In addition to grinding, the rotor system is also prone to failures such as misalignment, imbalance, cracks, etc. d...
