建立了复合金属氢分离膜热应力有限元分析模型。在不同工作温度条件下,对常规的平板式复合金属氢分离膜和本文所提出的新型镶嵌式复合金属氢分离膜内的热应力进行了详细的分析和比较。结果表明:在相同材料匹配及工作温度条件下,新型复合金属氢分离膜内沿交界面端面处向下逐渐减小的压应力会使该复合结构更加紧密牢固,从理论上证实了这种镶嵌结构能够大幅延长复合金属氢分离膜的使用寿命,为这种镶嵌结构复合金属氢分离膜的制备与应用提供了理论指导。
The finite element analysis model of thermal stress of composite metal hydrogen separation membrane was established. Under different working temperature conditions, the thermal stress in the conventional flat-panel composite metal hydrogen separation membrane and the new mosaic metal hydrogen separation membrane proposed in this paper were analyzed and compared in detail. The results show that under the same material matching and operating temperature, the compressive stress in the new composite metal hydrogen separation membrane that decreases gradually downward along the interface of the interface will make the composite structure more firm and firm, and it is theoretically confirmed that this mosaic The structure can greatly prolong the service life of the composite metal hydrogen separation membrane, and provide theoretical guidance for the preparation and application of the composite metal hydrogen separation membrane with the mosaic structure.
