摘　　要：基于模态分析理论,用振动测试的方法对HSK刀柄联结薄盘类刀具的工具系统进行了自由模态和工况模态试验,得到了HSK薄盘类工具系统的模态参数(固有频率、阻尼和模态振型),并与有限元数值计算得出的模态参数进行比较,验证了有限元模型构建的合理性,为进一步探究HSK工具系统的动态特性和进行结构优化、充分发挥高速加工中HSK刀柄的应用潜能提供技术依据。On the basis of modality analysis theory,a free modal text,a working modal text of the HSK tool holder and thin-disk cutter with the vibration measuring method were canied out.The modality parameters such as inherent frequency,damp ratio and modal shapes were gained. These modal parameters were compared with modal parameters, which was gained with the finite element method calculating method. The results verified whether the construction of the finite element modal is reasonable or not,and provided technical help for exploring the dynamic characteristics and structural optimization of HSK tool system, making the full use of HSK tool holder in high-speed machining.
