单自由度强迫振动是工程上较普遍的现象,本文仅用一般理论力学知识提出简便方法从建立方程到解出运动规律,并得出主要数据、结论可供应用时参考。 One-degree-of-freedom forced vibration is a relatively common phenomenon in engineering. This article only uses the general knowledge of theoretical mechanics to propose a simple method from the establishment of equations to the solution of the law of motion, and to draw reference for the main data and conclusions available for application.
