搭载反应釜的钢框架结构动力性能分析与设计建议
Dynamic Performance Analysis and Design Recommendations for Steel Frame Structure Supporting Reactors
反应釜工作时会对搭载其的钢框架施加较大的高频动荷载，但是目前此类钢框架结构的设计主要采用静力方法，忽略了反应釜运转对其的影响。提出了一种质量点和梁单元结合的模拟反应釜动力体系及其与钢框架连接的简化方法，可高效获得反应釜运转时钢框架的动力响应。基于现行标准《容器支座 第4部分：支承式支座》（NB/T 47065.4—2018），分析了反应釜支座底部节点与整体框架的承载能力，以及不同反应釜搅拌叶片旋转方向下的动力响应，并进行了该类结构的优化设计研究。结果表明：按现行标准设计的反应釜支座与连接节点为结构的薄弱部位，而基于钢材S-N疲劳曲线进行优化设计的支座能够使结构在正常工作范围内保持弹性；采用“相邻各异”的搅拌方向可以使反应釜搭载结构具有最小的弹性变形。研究结果可为相关设计工作提供参考。
Steel frame with the reactor is subjected to large and high-frequency dynamic load when the reactor is stirring. However， the design of this kind of steel frame structure usually adopts the static design method， and the static analysis cannot accurately describe the dynamic effect of the reactor acting on the structure. In order to efficiently research the dynamic effect of the steel frame supporting the reactor during the operation of reactor， a simplified modeling method is proposed in this paper to connect the reactor dynamic system with the steel frame using mass points and beam elements. Based on the current standard Vessel Supports—Part 4： Supporting Supports （NB/T 47065.4—2018）， the performance of the bottom joint of the reactor support， the overall structure， and the dynamic response of the reactor stirring blade under different rotation directions are studied， and the optimization design research on this type of structure is conducted. The results show that the vessel supports and joints designed according to the current standard are the weak parts of the structure， while the optimization design of the support based on the S-N fatigue curve of steel can ensure the structure remain within the elastic limit during normal operation. The method of "opposite of adjacent" used on setting the rotation direction of the reactor stirring can make the load-bearing structure have the minimum elastic deformation. This study provides some reference for the related design and research work.
