解析地推导了附加在正弦激励主系统上的n单元冲击阻尼器的对称两次冲击/质点/周期运动的精确解，并确定了其渐近稳定区域。数字计算机上的模拟运动和实验研究与力学模型，他们表现出良好的一致性与理论结果。研究发现，在运行机组的减振和噪声水平方面，适当设计的多单元冲击阻尼器比等效的单单元冲击阻尼器更有效。
The exact solution for the symmetric two impacts/particle/cycle motion of an n‐unit impact damper attached to a sinusoidally excited primary system is derived analytically, and its asymptotically stable regions are determined. Simulated motion on a digital computer and experimental studies with a mechanical model are presented, and they show good agreement with theoretical results. It is found that properly designed multiple‐unit impact dampers are more efficient than equivalent single‐unit impact dampers in regard to vibration reduction and noise level of operating units.
