华药集团厂房框架结构楼面振动有限元分析

Floor Broad Vibration Finite Element Analysis for Frame Structure of the Factory Building of North China Pharmaceutical Group

利用有限元软件对华药集团厂房结构进行了有限元建模并进行了模态分析,得出了厂房的自振频率。在此基础上对厂房进行了谐响应分析,得出了厂房楼面振动的原因主要是由于荷载增加,而不是由于结构与动力设备共振。

The finite element model and modal analysis is performed about the industry premise of North China Pharmaceutical Group by finite element procedure software. The frequency of vibration of the factory building is derived. Harmonic response analysis is made. A conclusion of vibration causes of the factory building ground is presented. The chief cause of vibration is not resonance of the equipment and the structure but the increment of load.
