| Abstract: | Based on the precise time integration method for structural dynamic systems provided by prof. Zhong Wan|xie, a precise direct integration method is proposed for the wave equation of sucker rod pumping systems in this paper. The special numerical examples are calculated with the precise direct integration,the implicit difference and the explicit difference respectively. In comparison with the others, the precise direct integration method is of higher precision and less run time. |
