二胡、板胡类琴杆振动分析及其制作选材的思考——琴杆在振动中的作用及选材思考

Thinking of Flutter Analysis and Making,Material Selecting of Erhu and Banhu——The Effect of Stick Vibrating and Thinking of Material

由边界条件和杆振方程的泛定解导出了振动频率表达式,指出了杆振各次泛频的不和谐性,对杆振与琴筒内空气振动的叠加效果进行了分析,指出了不同木材的琴杆具有基本相同的叠加效果,因而提出了开发新材料琴杆的设想。

We export vibration frequency from FanDing solutions of boundary conditions and stick equation,and show the discordance of overtones,analysis the composition effect of vibratory air between stick and tube.We get the result that sticks made of different kind of wood have basicly same composition effect,and put forward imagination of developing new material stick.
