| Abstract: | The general procedure and the method of the new kind of bar linkage are discussed and two important mathematics models are deduced. An application example, in which the varible length four bar linkage is used in beam pumping unit's design, is given to demonstrate the practical effect. By the comparison between the normal pumping unit and derivative pumping unit, the excellent performance and application prospect of the variable length four bar linkage is illustrated. |
