介绍了粘滞阻尼器的计算模型和计算分析方法,对有设备振动的多层框架结构工业厂房模型通过安装粘滞阻尼器来消能减振,根据结构中设备振动位置和最大位移位置设计出3组阻尼器布置方案,利用有限元通用软件ANSYS14.0对结构进行动力时程分析,并对得到的不同布置方案的减振效果进行比较。结果表明,阻尼器布置在闪蒸罐周围与最大变形处时消能减振效果相当,都能很好地控制振动,并验证了对于这种全钢结构工业厂房,附加粘滞阻尼器是一种有效的消能减振方法。
The calculation model and calculation method of viscous damper are introduced. The model of multi-layer frame structure industrial plant with equipment vibration can be dissipated and damped by installing viscous damper. According to the vibration position and the maximum displacement position of the equipment, Three sets of damper layout scheme, the use of finite element software ANSYS14.0 dynamic structure of the time-history analysis, and the results of the different arrangements of the damping effect comparison. The results show that the dampers arranged in the vicinity of the flash tank and the maximum deformation of the Department of shock absorption and vibration damping effect are quite good, can control the vibration, and verify that for this all-steel industrial plant, the additional viscous damper is a Effective energy dissipation method of vibration reduction.
