夹套反应釜开孔接管区的应力与疲劳分析

Analysis of Stress and Fatigue in Open Pore Nozzle Zone of Jacket Reactor

为了保证所设计的夹套反应釜的力学性能能满足实际工况的需要,并且达到工况所要求的使用寿命,对该夹套反应釜进行几何建模,利用ANSYS仿真软件,首先对其进行应力分析,模拟结果表明最大应力位于N_2接管与筒体连接处。然后,根据JB4732-95分析设计标准及相关疲劳计算,验证了结构设计的安全性和合理性,同时也为夹套反应釜的结构优化和后期维护提供了参考。

In order to ensure that the mechanical properties of the designed jacket reactor can meet the needs of actual working conditions and reach the required service life of the working conditions,this article geometrically models the jacket reactor.Using ANSYS simulation software,stress analysis was first carried out.The simulation results show that the maximum stress is located at the junction of the N2 tube and the barrel.Then,according to JB4732-95 analysis and design standards and related fatigue calculations,the safety and rationality of the structural design were verified,and it also provided a reference for the structural optimization and later maintenance of the jacket reactor.
