振动方程耦合类型的注记

A Note on Types of Coupling in Vibration Equations

采用动静法建立振动系统动力学方程,通过具体例子的讨论和一般情形的分析,论证了振动方程的耦合类型与系统广义坐标选取无关.

Some monographs on mechanics of vibrations asserted that the choice of generalized coordinates establishes the types of coupling in vibration equations.The method of kineto-statics is applied here to drive the vibration equation.The discussion on a specific example and the analysis of the general case demonstrate that the types of coupling in vibration equations are independent of the choice of generalized coordinates of the system.
