Analysis of two vibrating suction methods

In this paper, a novel vibrating method based on the principle of vibrating suction method is presented, which is called pulse vibrating method. To discuss this method in depth and evaluate its performance, simplified mathematical model based on some assumptions for both the previous sin vibrating method and the pulse vibrating method are built, and a new experimental platform is developed as well to verify the validity of the mathematical models. The experiments indicate that the experiments meet the mathematical model with only small deviation caused by some unknown factors. The experimental results also show that the pulse vibrating method is much better than the sin vibrating method for higher negative air pressure and less power consumption. At the end of this paper, conclusion is given and future work is proposed to further analyze the principle of the vibrating suction method.
