摘要
给出了一般初值条件下无阻尼自由度振系对简谐激励的响应公式，作为特例讨论了无阻尼动力吸振器，结果表明无阻尼动力吸振器并不能完全消除主系统的振动。
The response of undamped multi-degree-of-freedom systems to harmonic excitations for arbitrary initial conditions is presented. As a special case, the undamped vibration absorber is treated. It is demonstrated that undamped dynamic absorbers cannot suppress vibrations of the original systems.
