本文主要研究复杂振动问题的粘滞阻尼消能控制技术。介绍了粘滞流体阻尼器的构造、原理和计算模型;研究了支撑刚度对阻尼器耗能作用的影响,提出阻尼器的支撑设计在满足规范强度、刚度要求基础上,还应考虑支撑与阻尼器作为组合元件的协同耗能作用,为工程设计提供重要参考。结合江苏省某化工厂房的随机冲击宽频振动问题,运用动力测试、信号处理和有限元技术,对粘滞流体阻尼减振结构进行计算分析。结果表明,附加粘滞流体阻尼器的消能控制技术具有显著的减振效果,成为解决复杂宽频振动问题的有效手段,为类似工程提供借鉴和参考。
This paper mainly studies viscous damping energy dissipation control technology for complex vibration problems. The structure, principle and calculation model of viscous fluid damper are introduced. The influence of stiffness of support on the energy dissipation of damper is studied. It is proposed that the support design of damper should meet the requirement of standard strength and stiffness, As a component of the collaborative energy-consuming components, providing an important reference for engineering design. Based on the random impact broadband vibration problem of a chemical plant in Jiangsu Province, the dynamic damping, vibration damping structure of viscous fluid is calculated and analyzed by dynamic test, signal processing and finite element method. The results show that the energy-dissipating control technology with additional viscous fluid damper has significant damping effect and becomes an effective method to solve complex wide-band vibration problems, which can provide reference and reference for similar projects.
