Abstract

Using ball, roller and pendulum autobalancers as dual-frequency vibration exciters was proposed, corresponding designs were developed.

Kinematic diagrams of machines with different platform movements (plane or rectilinear translational, vibrational-rotational, plane-parallel, etc.), on which dual-frequency vibration exciters can be installed were proposed.

One of the technical solutions was tested by 3D modeling in SolidWorks CAD system using the CosmosMotion module.

Considered dual-frequency vibration exciters have complex structures, it is difficult to tune the resonance vibration frequency of the platform, etc. Therefore, a new method of excitation of dual-frequency vibrations in the resonance vibromachines, eliminating these disadvantages was developed in the paper.

For excitation of dual-frequency vibrations, using a special movement regime of the rotor with AB - quasiperiodic was proposed. In it, the rotor rotates at the resonance speed, and CW in AB can not catch up with the rotor since they are stuck at one of its resonance rotation frequencies.

One of the proposed technical solutions was tested in Solidworks CAD system using the Motion module. A 3D model of the vibration machine with vibroexciter in the form of ball autobalancer was developed and simulation has shown the following: the possibility of using autobalancer for the two-frequency vibration excitation in the resonance vibration machines was confirmed; features of dual-frequency vibrations can be varied within wide limits by changing the mass of corrector weights, unbalance mass in the auto-balancer housing, rotor speed.

Application of new vibroexciters will allow to create new vibromacnines with the dual-frequency vibration of the platform. The energy efficiency of these machines will be provided by the fact that the lower vibration frequency of the platform will coincide with its resonance frequency, which will provide intense vibrations of the platform necessary to perform the basic technological operation. Further intensification of technological processes will be ensured by self-cleaning of the screen and changes in the mechanical properties of the material processed by fast vibrations.
