【Abstract】 By using ANSYS, the distribution of the electronic gun’s temperature field and the distortion caused by its temperature are simulated and analyzed. Because of the complicated structure and the energy conversion inside the electronic gun, the different energy conversion form (conduction、radiation and convection) in the temperature field are taken into account. On analyzing the coupling between temperature field and structural distortion, reasonable result is produced. And it accords with the fact.更多还原
