The temperature distribution of the cylindrical shell irradiated by mobile laser beam is studied. Based on the method of Fourier series expansions, an analytical solution of the temperature field is deduced for the thin cylindrical shell, irradiated by intensive laser beam in four different motion modes，and programs are coded for computation. Numerical simulation results of this method are identical with those of finite element method. Finally, we analyze the effect of the rotating angular velocity and moving velocity on its temperature field under laser irradiation. The conclusion is drawn that temperature rise is most prominent in the case of periodic irradiation. Numerical results provide evidence for the laser resistant radiation of missiles in theory.
