| 摘 要： | 采用有限元ANSYS软件对偏滤器第一壁W/Cu FGM进行热应力模拟分析，并对其参数进行优化设计。结果表明，优化后的梯度层应力较无梯度层时得到了极大的缓和，最大等效应力值降低58%。最优化的梯度层层数为5，Cu浓度分布指数为0.4；同时在10 MW/m2的表面热流冲击下，表现出较好的抗热冲击能力

| Abstract: | Thermal stress simulation and optimization design of the parameters were performed for the W/Cu FGM of divertors by finite element ANSYS code. The results show that the thermal stress is decreased greatly by the introduction of the W/Cu FGM, and the maximum von mises stress is decreased approximately by 58%. The optimal parameters of the FGM are as following: the layer number of FGM is about 5 and the distribution exponential of Cu volume content is about 0.4. Meantime a good heat resistance is shown with a surface temperature below 800 oC under the 10 MW/m2 surface heat load |
