Abstract：The consumption of metal rubidium in rubidium lamp is the main factor determining the working life of rubidium atomic clock. In order to predict the working life of rubidium lamp, based on the similarity of transient heat conduction equation and unsteady mass diffusion equation in mathematical form, a rubidium diffusion model was established to predict the working life of Schott 8436 glass rubidium lamp by using the finite element software ANSYS, The accuracy of the model is verified by comparing the predicted results of the finite element model with the seven-year rubidium measurement data of Wuhan Institute of physics and mathematics, Chinese Academy of Sciences. Through the verified finite element model, the influence of Schott 8436 glass rubidium bulb volume and external profile curvature on rubidium consumption under the same diffusion area is discussed. The relevant results provide theoretical support for the selection of glass rubidium bulb.
