Abstract: This study presents a simple numerical method for designing sucker rod taper percentages. The method is more general than analytical solution , the it is quite adequate for the complex rod string load formulas. Its validity is verified through the Practical example with rod load formulas and design requirements.

Key words: Rod string design, Fatigue strengh, Numencal method
