Combined rotation system assembly online dynamic balance detection system and method

Abstract

The invention provides a combined rotation system assembly online dynamic balance detection system and method. The detection system comprises a dynamic balance analysis system, a data acquisition system, a detection sensor and a combined rotation system. A reflective marker is attached to a rotor. A rotation speed test sensor is installed on a non-rotating component, and is aligned to the reflective marker on the rotor. Vibration test sensors are mounted on respective bearing seats. The detection sensor is connected to the data acquisition system. The data acquisition system is connected to the dynamic balance analysis system. The detection method, by using a vector coordinate calculation method, performs dynamic balance detection on the combined rotation system, and configures a weight toeliminate the vibration caused by mutual response after the assembly of the rotor. The detection system and method can meet the requirements for convenient online dynamic balance operation, high accuracy and good balance effects, can be used for the balance of rotors in various industries such as machinery, aviation and electric power, contributes to the vibration reduction, the noise reduction and the wear reduction of the whole system, and prolongs the service life of a machine.

Description

technical field [0001] The invention belongs to the technical field of mechanical vibration and rotors, and in particular relates to an assembly-line dynamic balance detection system and detection method of a combined rotary system, which can be widely used in rotor dynamic balance detection in machinery, aviation, electric power and other industries. Background technique [0002] In recent years, the development of modern industry has been rapid. In order to ensure the stable operation of mechanical equipment, prolong its life, and relieve fatigue, the vibration of equipment has become the focus of everyone. Generally speaking, vibration tends to bring many hazards. For example, the vibration of machine tools will reduce the machining accuracy of the workpiece and increase the surface roughness; the excessive vibration of the motor rotor will cause abnormal operation, and the vibration of the ship will affect the accurate use of the instruments on board; the alternating str...
