| Abstract: | In this paper, spatial doma ferential equ tions, an eff in is discret ations, and method of lines is used to solve the vibration problems of beam. The ed by method of lines, the problem is transformed into ordinary dif- then the fourth-order Runge-kutta method is used to solve the equa- icient numerical method is obtained to deal with the vibration problems of beam. numerical examples show that the method is better. |
