摘要： 著作［1］中已有论述的调谐原理（TMD）是动力消振器技术的基础，近30年已广泛用于建筑、结构、桥梁等各个方面的抗风振和抗地震。现在调谐技术又用在网球拍上。为此对网球拍的弯曲自由振动进行测试，得到一阶固有频率，再用传递函数和相干函数分析，确信这个数据是可信的，最后对网球拍减振球的振动方程进行分析，得到减振球系统的固有频率与一些参数的定性关系。

Abstract: The TunedMassDamper (TMD) technique, presented in Literature ［1］, is based on the vibration absorption principle. In recent three decades, it has been applied to many fields such as structure and bridge engineering for mitigating vibration excited by wind and earthquake［2］. Recently, The TMD has been applied to tennis rackets for vibration control. In the present paper, the free vibration of a tennis racket is tested and then the first natural frequency is obtained by the powerspectraldensity analysis. The results are verified by the analysis of transfer function and correlation function. On the other hand, the equation of motion of a massstring as a simplified model of tennis racket with TMD is given, and its natural frequency is obtained.

Key words: vibration and wave, TMD, tennis racket, PSD analysis, correlation function
