论文部分内容阅读
本文主要由三个部分所组成。 在第一部分里,导演出单自由度系统,无阻尼和阻尼强迫振动矢量图曲线之微分方程式(直角坐标与极坐标二情形),并给出相应的起始条件。 第二部分阐述一般矢量图曲线微分方程式之应用,并列举了例题。 最后部分,作者比较详尽地研讨了强迫振动矢量图之一般性质,与苏联拉宾诺维奇(И.М.Рабинович)教授的单自由度系统强迫振动矢量图作了一些比较,并论述了作者所提出的矢量图与拉宾诺维奇矢量图二者间的相互关系。
This article is mainly composed of three parts. In the first part, the director presents a single degree-of-freedom system with no damping and damping. The differential equations that force the vibration of the vector graph curve (right angle coordinate and polar coordinate two cases) are given and the corresponding starting conditions are given. The second part elaborates the application of general vector graph differential equations and lists examples. In the last part, the author studied the general nature of the forced vibration vector diagram in detail and compared it with the single-degree-of-freedom system forced vibration vector diagram of Prof. Rabinovich (И.М.Рабинович) and discussed the author. The relationship between the proposed vector and Rabinovich vector.
