摘要
以古琴为研究对象,在ANSYS中建立古琴有限元模型.通过模态仿真和计算,得到了相应的模态振型及固有振动特性.同时为了获得古琴的实际振动特性,进行了模态测试,实验结果和仿真结果相符,验证了模型的正确性,为后续古琴的进一步动力学研究及设计提供参考,为探索科学化制琴技术提供了依据.
The finite element modal of the Guqin structure was established with ANSYS. Through the model simulation and calculation, the modal shape and natural vibration characteristics were obtained. In order to obtain the actual vibration characteristics, the modal test was done. Then the model was confirmed by modal experiment. With this analysis, the dynamic characteristics of the Guqin were known. It provides reference for further kinetic studies and optimization to the manufacture of Guqin.
