摘要
以往对于火力发电厂的筒仓结构通常采用分块简化方法进行分析计算,大多数计算结果均十分保守。本文剖析了筒仓的一般设计前处理过程,包括荷载输入以及有限元模型建立。以湛江新建筒仓为工程实例,建立不同的模型,通过对比分析,揭示了一般电厂筒仓结构有限元模型建立的注意要点及设计思路,供今后筒仓结构设计以及研究人员参考。
The silo structures of coal- fueled power plants are analyzed with separatehandy methods, most of the calculation result are conservative. In this paper, the former management process of the silo will be anatomized in detail, including the load input and the establishment of the FEA. The ZhanJiang silo will be illustrated, the key points and the design method about the establishment of the FEA will be put forward for the silo designers and investigators by analysis comparison with different model.
