摘要: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.

关键词: 振动力学, 耦合, 广义坐标

Abstract: 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.

Key words: mechanics of vibration, coupling, generalized coordinates
