摘要
采用化学气相工艺技术,在碳纤维布表面原位生成具有特殊性能的微观涂层,进而将这种纤维布引入到乒乓球拍底板的夹层结构中,实现了底板动特性的调节.采用有限元仿真技术和非接触式模态测试技术,对引入特种纤维夹层的乒乓球拍底板开展了模态分析和测试.对应不同的纤维夹层,底板的一阶和二阶固有频率分别可以在 115～127 Hz范围内和 179～198 Hz范围内调节.揭示了特种纤维夹层对底板动特性的影响,证明了有限元仿真技术和非接触式模态测试技术在底板动特性研究中的可行性,为更科学、更全面地设计乒乓球拍底板提供了新的思路.
Abstract
Several series of special fiber laminates with different performance were designed and fabricated by chemical vapor deposition method.The dynamic responses of table tennis blades were found adjustable with the inclusion of different fiber laminates.The dynamic characteristics and mechanisms of the blades were analyzed and measured by finite element method(FEM)and non-contact mode measurement method.The first and second or-der frequencies of the blades can be adjusted in the range of 115-127 Hz,and 179-198 Hz,respectively,which cover the performances of most popular market products.The FEM and non-contact mode measurement method are both proved to be feasible on designing and studying the characteristics of table tennis blades.
