摘要
不平衡量的存在对机床工具系统在高速旋转下的影响较大。介绍了动平衡的基本概念,基于比较分析的视角,对HSK与BT工具系统动平衡性能从理论方面进行了比较分析,同时进行了数值模拟仿真比较分析。分析结果表明:与BT工具系统相比,HSK工具系统允许的不平衡量更小,所造成的不平衡离心力更小,引起的结构变化更微弱,HSK工具系统高速动平衡性能更好。
The existence of unbalance quantity has a great influence on the tool system in high speed rotation. The basic theoretical of dynamic balance was introduced. Based on the comparative analysis,theoretical of dynamic balance performance of HSK and BT tool system was compared and analyzed. And the numerical simulation was analyzed. The result indicated that compared with the BT tool system,smaller amount of imbalance can HSK tool system allowed,and it had a smaller centrifugal force caused by the imbalance,and had a weaker structural change which caused by unbalanced centrifugal force. HSK tool system shows a better dynamic balance performance.
