| 摘 要： | 首先给出了只受干摩擦作用的阻尼振动的一个佯谬,然后通过对这种振动的理论分析,说明其数学解的条件,归纳出这种振动规律的位移、速度、能量的一般数学表达式,进一步论述了这种振动所满足的功能关系,并通过位移—时间图像形象地说明了这种振动规律,消除了原来的佯谬.

| Abstract: | In this article,a paradox on damped vibration which is only acted upon by dry friction is given.Then,after the analysis of damped vibration,we shows the conditions for its mathematical solution and provides the general mathematical expression which is obeyed by the movement,velocity and energy of the damped vibration.The function relationship satisfied by the vibration is also discussed here.Based on movement-time curve,we shows the vibration law and eliminate the original paradox. |
