New Online Auto Balance Device for High-speed Electric Spindle System

摘要

Mass imbalance is a common cause of vibration in rotating machinery, which can damage the rotary system or the whole system. To solve this problem, the best balanced measure is to perform real-time online dynamic balance compensation during operation. In this study, a new type of high-speed electric spindle system with online auto balance device and associated control circuit is developed by integration technology. It achieves that the device have short response time, high efficiency, energy saving features and other advantages. To verify its validity, co-simulation program of ADAMS/controls and Matlab/Simulink is developed to conduct virtual prototype balance simulation. The results show that vibration near the 10000 r/min reaches reduction of 95%, and high balance quality standards G0.4-G1 are also achieved through adjusting the angle of balance device and controlling vibration accurately.
