摘要
研究单自由度系统受简谐力激振时散体团冲击减振的规律。对冲击体自由运动间隙取不同值时冲击消振的稳定冲击范围及运动间隙、激振力、冲击力与结构速度响应、消振效果的关系进行了试验研究,推导了在周期冲击力作用下单自由度系统响应的计算公式,并在此基础上讨论了冲击力对多自由度系统可能产生的影响和粘弹性阻尼在消振中的作用。
The vibration attenuation of a soft impact damper for the simple degree of freedom system is studied.Having various gaps of impacter and structure,the stable range of vibration attenuation as well the relationship of exciting force,im- pact force and structure response,attenuation effect is investigated experimently. Furthermore,the algorithm expression of the periodic impact response for single degree of freedom system is developed.
