This paper builds a model of the finite element calculation for the CPT bulb, employing the software SAP5P to calculate the temperature stresses of the bulb when it is being heated and exhausted in the furnace. The useful temperature stress distribution for the bulb under the circumstance of varied temperature has been obtained. In the meanwhile this paper illustrates why there are different crack points on the bulb in the stages of elevated temperature and lowered temperature, thus laying the foundation for the reasonable determination of the temperature curve in production and the optimum design of the bulb structure.
