摘要
以凤滩水力发电厂一副厂房为例,基于梁元和壳元建立空间有限元仿真模型计算了厂房的动力特性和几种工况下的动力响应,并进行了相应工况的动态测试,对测试结果与计算成果进行了比较。研究表明,测试结果可靠,分析模型正确,找到了该厂房砖混结构开裂为振动过大所致,提出了相应的振动控制策略,为类似结构的振动安全性研究提供了参考。
In this paper, a 3D FEM model is built up for the analysis of the dynamical characteristics of a industrial structure, the tested results on the dynamic properties of auxiliarg plant of the the structute are compared with its results computed by the FEM model, it is shown that both the results are agreed. Finally, vibration control measures of the concrete masonry plant are suggested for reducing vibration of the plant .
