Abstract:

As the currently developed oscillation mechanism generally does not have adjustable amplitude, a circular oscillation mechanism with adjustable amplitude is designed. It contains an eccentric motion mechanism and an adaptive dynamic balance mechanism. Dynamic simulation and analysis are carried out on the eccentric motion mechanism. Experimental results show that 0~50 mm adjustable amplitude and 2~36 rad/s adjustable oscillation frequency can be achieved simultaneously. Unbalance quality of the table causing adverse effects can be compensated by the adaptive dynamic balance mechanism to increase life of the die. Its oscillation amplitude can be changed easily, conveniently and quickly, with simplicity, compact mechanism, rigid connection, strong bearing capacity and easy maintenance. It is expected to be used widely in biological engineering.
