Aimed at the problems of usually the shortrange and highload linear reciprocating mechanism is of serious energy comsumption and its frequency is difficult to improve, an air spring was introduced to boost the mechanism. The motion and energy consumption features of the linear reciprocating mechanism were analyzed in detail. A “swingup control algorithm” was proposed to solve the problem that the need of driving force was increased at the initial stage after the introduction of the elastic energy storage device. The experimental results show that: in the case of realizing the same reciprocating frequency, the introduction of an air spring not only reduces the vibration, impact and noise in the system, but also effectively decreases the demand for thrust force of linear motor, and reduces the system energy consumption. The experimental results verify the theroetic analysis is correct.
