摘　　要：基于GB/T 151-2014《热交换器》标准对固定管板式换热器的管板进行计算,得到了不等径固定管板的3种计算方法,并确定最优计算模型及厚度参考范围。采用二分法对管板厚度进行轻量化设计,并结合有限元仿真进行分析设计验证。结果表明:轻量化不等径固定管板质量由1351kg减少至1009kg,且应力分布满足JB4732—1995《钢制压力容器——分析设计标准》的评定要求。Based on the GB/T 151—2014 Heat Exchangers standard,three calculation methods for fixed tube sheet heat exchangers with unequal diameters were obtained,and the optimal calculation model and thickness reference range were determined.Adopting the binary method for lightweight design of tube sheet thickness,and using finite element simulation for analysis and design verification.The results showed that the lightweight fixed tube sheet with unequal diameter reduced its weight from 1351 kg to 1009 kg,and the shear stress distribution met the evaluation requirements of JB 4732—1995 Steel Pressure Vessels——Design by Analysis.
