Research And Application Of Composite Trajectory Of Plane Rotary Vibration Sieves

The plane rotary vibration sieves are widely used in the grain and oil processingenterprises due to their features of compact structure, smooth operation, low powerconsumption and high sifting efficiency. There is an elastic stopper device at the end of itsbody of the plane rotary vibration sieves used in today，therefore, the overall organizationalis very complex, and existing the phenomena of material deviation in the process ofscreening which causes many adverse phenomenon such as reducing the efficiency ofscreening, forcing unbalance, the trajectory not flexible etc. And these phenomena bringabout some harmful effects, for example the uneven abrasion of screen lattice, and shortenthe service life of the screen lattice.In view of the problems, first of all, this paper will base on the present research, andput forward mechanism design theory of the composite track plane rotary vibration sieveswithout mechanical constraining. Young’s modulus and material loss factor are twoimportant dynamics parameters, but there are lack of research on Young’s modulus andmaterial loss factor of the glass steel suspender. This paper will take the glass steelsuspender which is widely used in the plane rotary vibration sieves as the research object,attempts by the contrast method, that is contrast between the experimental results andnumerical simulation results, and then get the Young’s modulus and loss factor of the glasssteel suspender, providing parameters for engineering design. Finally, this paper willestablish the virtual prototype model of the plane rotary vibration sieves, and carry outsteady state dynamic analysis of mechanism, and then the atlas of the sieves under differentcombination of the hanging number and hanging length will be obtained by studying therelationship between the position of eccentric rotor on the sieves and the trajectory of thesieves. In the practical engineering application, we will select the appropriate technologicaltrajectory according to the process requirements and then determine the location of theeccentric rotor on the sieves. And then, transient dynamic analysis of mechanism will be executed to study how the hanging length and number impact on on the transientcharacteristics, so as to find out the suitable combinations of the hanging length andnumber.
