摘　　要：利用有限元的热-固耦合分析方法确定了发酵罐危险部位,以及最大应力、应变值,对计算结果进行了分析,依据计算结果进行了罐体结构强度的安全校核,分析结果表明发酵罐样机罐体强度安全,研究方法及结论对发酵罐应力分析、强度评估、结构优化机制造具有实际指导意义与借鉴价值。In this paper, the dangerous position of tank, the maximum value of stress and the strain value are determined with the thermal-solid coupling analysis method of the FEA, and the calculated results are mainly analyzed. Based on these calculated results, the security and structure strength of the fermentation tank are checked. The analysis results show that the structure strength of tank-body of the prototype meets the safety requirements. The research method and conclusions can provide more important guidance and references for the stress analysis, the intensity assessment, the structural optimization and manufacture of fermentation tank.
