Field Balancing Test System Study Based On LabVIEW

Rotor imbalance is especially high-speed rotating machinery vibration of rotating machinery main exciting force.also lead to and aggravate the other important reason for rotor fault.Today,Efficient machinery and equipment is moving in the direction of high-speed rotating movement as most of the main form of mechanical systems.Therefore,the balancing of the rotor should be given high priority.In this papar,various type of rotor balancing of principles and methods of a systematic exposition analysis and research.In conclusion,Advantages and disadvantages of the previous development of field balancing instrument based on virtual instrument technology,digital signal processing technology comvined with field balancing.Balancing the rotor of the test system development.Field application show that the system is stable,accurate and fully meet the standard test applications.Introduced the backgroud field of dynamic balancing test,balancing test,including the field of foreingn and domestic status and lack of. Described in detail in the virtual instrument in balancing application and programming software image LabVIEW. Highlighted in the single-plane dynamic balancing of rigid rotors and dual-plane dynamic balancing test methods, and the system's testing program. Introducing correction methed of flexble rotor.Introfucing the menthod of harmonic components.The system related to the hardware design and matching. Analysis of the characteristics of the sensor, model.. Do a test system based on access to information work and to determine the placement of the sensor.. Cross-correlation analysis using signal processing of vibration signals to extract the amplitude and phase unbalance. Of data collection, data management, time and frequency domain analysis, phase analysis, one school and two schools face balancing the positive equilibrium was modular designDeveloped baded on the virtual balancing LabVIEW online testing system.. Realize the amount of vibration amplitude and phase measurement and the calculation of the required weight distribution. Realize the dynamic unbalance test.Balance test software development, online data processing and analysis, test data storage and management...
