机忻魅振动 （2学分）内容撮要：单自在度系统：自在振动、有阻尼受迫振动和无阻尼受迫振动；
Mechanical vibration (2 credits) Summary: The single degree of freedom systems: free vibration, forced vibration damped and forced vibration damping;
推导了弹性轴向行进索无阻尼线性受迫振动解，用数值方法求得有阻尼行进索受迫振动和自激振动响应。
The exact solution of linear, undamped forced vibration response is developed, and the damped forced vibration as well as the self-excited oscillation are obtained numerically.
本文在工科物理实验中，用计算机动画来研究弹簧振子的无阻尼振动、阻尼振动及受迫振动。
It's exploratorily discussed that computer cartoons are used to study the non-evanescent vibration, evanescent vibration and forced vibration in students' physical experiments.
