Abstract

The paper reports the consideration of technolo-gical vibrating machine dynamic properties on the ba-sis of the model as a mechanical oscillating system with two degrees of freedom having in its structure a device for motion conversion (DMC) forming addi-tional inertial couplings at the simultaneous action of two external harmonic factors. The purpose of investi-gations consists in the development of the method for the formation of simulators ensuring possibilities for dynamic states assessments at the use of such parame-ters of a state as a relation of ties dynamic reactions between a supporting surface (source of kinematic dis-turbance) and a work apparatus.
 For investigations there is used a method of structural mathematical modeling within the limits of which the mechanical oscillating system is compared with a structural circuit equivalent dynamically a sys-tem of automatic control. There is offered a technology of starting simulators transformation ensuring a defini-tion of tie dynamic reactions in characteristic points of element contact connection of the system at the simul-taneous action of two factors. It is shown that the joint action of two external disturbances does not change frequencies of characteristic oscillations in the system, but affects considerably its dynamic properties. There are shown diagrams of the dependences of motion points and values of tie dynamic reactions in characteristic points upon a frequency of external im-pact. The manifestations of new dynamic effects in the interactions of system elements between each other as a formation of additional modes of oscillation dynamic damping and amplitude-frequency characteristics (AFC) of a certain type are shown. Dynamic effects predetermine potentialities of a purposeful tuning of vibration fields. It is shown that the value of the shown DMC mass of affect substantially dynamic properties of the system that can be used both for motion parame-ter control, and for the assessment of tie dynamic reac-tions arising at that in the system.
