中文摘要：

在高温液态锂铅包层结构设计、热工水力学设计和中子学计算基础上，建立包层的三维有限元分析模型，应用商用有限元软件ANSYS对高温液态包层进行热-力结构耦合分析与应力评定。经计算第一壁材料ODSRAFM钢最高温度635℃，最大VonMises应力379MPa；包层结构材料RAFM钢最高温度508℃，最大Von Mises应力175MPa；FCI材料最高温度950℃，最大Von Mises应力218MPa。初步的分析结果表明结构设计方案是合理、可行的。

英文摘要：

On the basis of the structural design, thermal-hydraulic design and neutronics analysis, the 3D finite element model of the HTL（High Temperature LiPb Blanket） was developed for numerical simulation by using the finite element code ANSYS. The struc- tural mechanics analysis was presented for the blanket with the result of the maximal temperature 635 ℃, 508 ℃, 950℃ and the maximal Von Miss stress 379 MPa, 175 MPa, 218 MPa, respectively in the fist wall, blanket structure and FCI materials. The preliminary stress analysis showed that the blanket structure design was reasonable and feasible.
