摘要
复杂环境下卡箍法兰系统工作的稳定性和安全性是研究过程中至关重要的一个环节,为研究高温高压对卡箍法兰性能的影响,该文采用SolidWorks软件建立物理模型,基于ANSYS Workbench软件分析热应力耦合对结构的影响。研究结果表明,(1)卡箍孔板法兰的内壁面温度最高,且由内而外,温度逐渐减低,最低温度位于螺柱上。(2)卡箍孔板法兰整体最大应力位于球面螺母与卡箍的接触面上,为739.73 Mpa。密封环上的唇部应力大于密封比压,符合密封环的密封性能的要求。(3)密封环的线性等效应力模拟结果对比许用应力准则,强度满足安全要求,不会发生塑性垮塌。
The stability and safety of the clamp flange system in complex environment is a very important link in the research process.In order to study the influence of high temperature and high pressure on the performance of the clamp flange,the physical model is established by using SolidWorks software,and the influence of thermal stress coupling on the structure is analyzed based on ANSYS Workbench software.The results show that,①the inner wall temperature of the clamp orifice plate flange is the highest,and from the inside to the outside,the temperature decreases gradually,and the lowest temperature is on the stud.②The maximum stress of the clamp orifice plate flange is located on the contact surface between the spherical nut and the clamp,which is 739.73 Mpa.The lip stress on the sealing ring is greater than the sealing specific pressure,which meets the requirements of the sealing performance of the sealing ring.③Compared with the allowable stress criterion,the linear equivalent stress simulation results of the sealing ring show that the strength meets the safety requirements and plastic collapse will not occur.
