摘要

为解决高速主轴由于不平衡导致的振动问题

提出了一种基于动力学模型的高速主轴动平衡方法

其仅需在工作转速下采集振动响应数据

且无需停机试重.该方法通过对连续分布的不平衡量进行集中化处理

缩减不平衡响应与不平衡量之间的关系矩阵

可以在高速主轴的任意2个位置上实现双面平衡.研究结果表明

该方法能够准确地识别出等效集中的不平衡量

且所识别的由等效不平衡量引起的振动响应与原始振动响应基本一致.因此

添加配重后可使主轴各位置不平衡振动得到有效地抑制.

Abstract

A new high-speed spindle balancing method based on dynamic model is presented to suppress vibration from imbalance. It only needs to collect data of vibration response at operating speed without trial weights. Concentrating the continuously distributed imbalance and reducing relationship matrix between unbalance response and imbalance

the new method enables to achieve double plane balance of the high-speed spindle in two arbitrary positions

which identifies the equivalent concentrated imbalance accurately

and the vibration response induced by the identified imbalance is similar to that induced by original continuously distributed imbalance. Adding the counterweight

the imbalance vibration of spindle is suppressed effectively.
