阻尼作用下的弦振动研究

Studies on damped oscillation of string

在求解阻尼作用下的弦振动方程稳态解的基础上 ,讨论了有阻尼情况下弦上各点的振动情况以及策动力如何传递能量以补充由于阻尼所引起的能量损耗的过程 ,它将使我们进一步地了解弦振动的实际过程 ,并对相关的研究、测量和教学工作提供参考和指导意见 .

Based on the steady solution to the equation for the vibration of the string,this paper discusses the vibration of all the points along the string under damped oscillation and how the driving force supplies energy to replace the energy lost in the course of damping.This enables us to understand further the practical process of string vibration and facilitates reference to related research,measurement and teaching work.
