摘要

所有高速旋转系统

动平衡是一个关键问题.针对高速电主轴

研究了不平衡振动抑制措施

设计了在线动平衡装置.首先

利用电磁场的耦合作用

无接触地在加重平面处形成与所需离心力等效的旋转电磁力

实现在线实时精密补偿;其次

考虑到此时空旋转电磁力能耗大、机械结构内应力大的缺点

运用影响系数法控制策略

在平衡盘上利用旋转极坐标合成矢量力

驱使附加质量块移动使转子质心落回旋转中心

同时时空旋转电磁力消失

主轴系统在极坐标合成力的作用下实现最终动平衡.通过ADAM S与M ATLAB联合仿真

证明了振动在10 000 r/m in速度点附近减少了95%

达到了高速主轴的平衡品质标准.

Abstract

The dynamic balance is a key question in high-speed revolving systems.The article has studied the unbalanced vibration abatement measure of the high-speed electric main axle and designed a compound on-line dynamic balance device.First

by electromagnetic field coupling

an diameter-directed rotating electromagnetic force can be formed on the weight-added plane to realize a real-time and on-line precision compensation.Secondly

considering that the rotating electromagnetic force consumes a lot of energy and its mechanism internal stress is heavy

we used the influence coefficient controlling strategy

driving the quality block to migrate with the vector force composed by the revolving polar coordinate on the balance plate.Thus

the rotor's barycenter was in its center

and with the rotating electromagnetic force vanishing

the main axle system realized the final dynamic balance.Moreover

the simulation result by Adams and Matlab proves that the vibration can be reduced 95% at the speed of 10 000 r/min

and the design achieves the balance standard of high-speed main axles.
