【摘要】 选用比动态弹性模量这一动力学参数作为实验的研究指标来分析材料的动态响应,对不同铺层情况下的复合材料古琴面板和底板的比动态弹性模量进行测量,并与木质古琴的实验结果作比较。结果表明,特定铺层情况下的复合材料古琴与木质古琴的动态响应相近,证明了复合材料作为替代材料制作古琴的可行性,为进一步了解复合材料声学特性提供了依据。更多还原

【Abstract】 We choose the specific dynamic elastic modulus as an index to judge the dynamic behavior of material. In this article,we conducted the experiment to study the specific dynamic elastic modulus of the faceplate and baseplate of composite Guqin with different plies and compared with wooden Guqin. From the results,we can get the specific plies which are in agreement with wooden Guqin in dynamic behavior. It demonstrated the feasibility of using composite materials to make Guqin,and provided a basis of studying the sound characteristics of composite materials.更多还原
