Dynamic Performance Analysis and Design Recommendations for Steel Frame Structure Supporting Reactors
摘要
Abstract
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.关键词
