摘要
采用有限元分析软件ANSYS模拟分析了W/Cu单体模块在ITER稳态热流和瞬态热流叠加下的温度分布和应力分布。结果表明,在稳态热流下,结构安全可靠;但在瞬态热流加载下,钨材料表面发生塑性应变,发生塑性应变的临界热流密度为320MW·m 2(持续0.5ms)。模拟结果对ITER偏滤器的设计和升级改造具有一定的借鉴意义。
Thermo-mechanical analysis was performed under the superposition effect of steady state and transient heat flux for the ITER W/Cu mono-block model by finite-element analysis code ANSYS. Numerical results proved the structure to be safe and reliable under the steady state heat flux, while under the transient heat flux, there occurred plastic deformation on the surface of W, and the corresponding heat flux was 320MW·m 2（lasts for 0.5ms）. The results can be useful for the design and improvement of ITER divertor.
