摘　　要：通过有限元计算对高温、高压环境下TBM的整体框架结构强度进行了分析。为提高分析效率,通过合理简化,得到1/3的TBM整体框架结构模型,并以等效质量的形式考虑氚增殖子模块对整个模型的影响。对模型施加300℃高温及8 MPa的氦气压力,分析表明1/3的TBM模块整体框架结构设计基本满足高温、高压(300℃,8 MPa)载荷条件下的强度要求,但加强筋处应力偏大,其结构可进一步优化。Structural strength analysis is carried out using finite element calculation for the frame structures of China Helium Coolant Solid Breeder Test Blanket Module(CH HCSB TBM) which is exposed to high temperature and high inner pressure. For improving efficiency, the 1/3 TBM model without submodules is derived, and mass-equivalent method is adopted to involve the effect of submodules. When this model is exposed to 300 ℃ and the 8 MPa helium pressure, results show that this TBM structure design fulfills the strength requirements of the CLF-1 material at 300 ℃/8 MPa. However, it also shows that the Mises stress is a bit large at the two stiffeners, indicating further structure optimization is expected.
