WebForced vibration is the term used to describe when an external periodic force causes a body to vibrate. Here, the system is given external energy, which causes the vibration's amplitude to damp yet keep constant. In forced vibration energy gets added to the vibrating body. The forced vibration is either damped or undamped. Webvibration. The vibration also may be forced; i.e., a continuing force acts upon the mass or the foundation experiences a continuing motion.
