Impulse excitation of vibration
WitrynaA mass attached to a spring can be set in motion by applying a force either to the mass or the spring. We consider a problem where a short impulse is applied to the spring in an attempt to project the mass at maximum speed. The problem arises when swinging a flexible golf club or a fishing rod, both of which vibrate at low frequency as a mass … Witryna本文介绍了脉冲激励的试验原理；根据理论分析，着重讨论了用脉冲激励法测量结构频率响应函数时所涉及到的有关问题，并就具体问题相应地提出了有效的处理方法。
