To implement GB/T 4732.3—2024 Pressure vessels design by analysis-Part 3:Formulae method,this paper systematically elaborates on the development practice and key considerations of the fixed tubesheet heat exchanger module in the SW7 software.The research focuses on several issues not mandated by the standard but of significant engineering significance,and conducts theoretical modeling,formula derivation,and functional expansion.The main contents include:Expanding the mechanical models to include the tubesheet embedded welding structure and the flat cover with a central nozzle opening,enhancing the engineering applicability of the software;Incorporating the effects of thermal bending deformation caused by temperature differences across the tubesheet thickness and the differential thermal expansion between the tubesheet and flange materials,achieving refined analysis of thermal loads;Based on the deformation coordination relationship of the flange-bolt-gasket system,proposing a method for determining a single bolt preload load that meets sealing requirements under multiple operating conditions;Innovatively proposing a nonlinear analysis theory for the variable‑stiffness elastic foundation plate,revealing the coupling mechanism by which tubesheet bending leads to a reduction in the axial stiffness of peripheral heat exchange tubes;Improving the stress evaluation system for key components such as the channel shell and shell‑side shell ends,and the flat cover,while clarifying the priority conditions for stability checks of heat exchange tubes and the criteria for selecting strength theories under biaxial stress states.SW7 software is not only a programmatic implementation of the new analysis and design standard,but also a beneficial supplement and engineering extension to the standard content.The release of its trial version is expected to promote the advancement of industry technical level.

为贯彻落实GB/T 4732.3—2024《压力容器分析设计 第3部分:公式法》,系统阐述了SW7软件中固定管板式热交换器模块的开发实践与关键考量,研究围绕标准中未要求但具有重要工程意义的若干问题,开展理论建模、公式推导与功能扩展工作。主要内容包括:扩展管板嵌入焊结构、平封头中心开孔接管等力学模型,提升软件的工程适用性;引入管板厚度方向温差热弯曲变形及管板与法兰材料热膨胀差异的影响,实现热载荷的精细化分析;基于法兰-螺栓-垫片系统的变形协调关系,提出满足多工况密封要求的单一螺栓预紧载荷确定方法;提出变刚度弹性基础板非线性分析理论,揭示管板弯曲导致周边换热管轴向刚度下降的耦合作用机理;完善管箱与壳程筒体端部、平封头等关键部位的应力评定体系,明确换热管稳定性校核的优先工况及双向应力状态下的强度理论选用原则。SW7软件不仅是对新分析设计标准的程序化实现,更是对标准内容的有益补充与工程化拓展,其试用版的发布有望推动行业技术水平的提升。
