本文给出了带有冲击阻尼器的正弦激励n自由度系统稳态运动的精确解。激励和阻尼都可以独立地施加到系统中的任何点。模拟计算机和力学模型的实验研究证实了理论结果。将分析结果应用于现代10层建筑的集中参数表示，并确定了各种系统参数，包括振型、激励频率、阻尼器位置和力位置的影响。结果表明，冲击阻尼器是一种有效的装置，用于减少多自由度系统的振动，特别是在结构，如高R
An exact solution is presented for the steady-state motion of a sinusoidally excited n-degree-of-freedom system that is provided with an impact damper. Both the excitation and the damper may be independently applied to any point in the system. Experi mental studies with an analog computer and with a mechanical model corroborate the theoretical results. Results of the analysis are applied to the lumped parameter repre sentation of a modern 10 story building, and the effects of various system parameters, including mode shape, excitation frequency, damper location, and force location are determined. It is found that the impact damper is an efficient device for reducing the vibrations of mullidegree-of-freedom systems, particularly in structures such as tall R
