Abstract
The Guzheng string vibration model have been simplified into the bounded string vibration model, and the dynamics analysis of the vibration of plucking and sweeping strings has been established firstly. Then, the dynamic model of the process has been built that the string vibration passes from the bridge to the Guzheng panel. Finally, the accuracy of the model proposed in this dissertation has been verified through the comparison of the numerical results of between using the Matlab simulation and the experiment. The work of this paper provides a reliable theoretical model for the analysis of the string vibrating and the bridge of Guzheng. And it solved the problem of the simplification of the structural model in analyzing the Guzheng vibro-acoustic characteristics, and will provide more or less support and guidance for improvement of future Guzheng.
