High requirements for reliability, durability, power and productivity of vibrating machines are directly determined by the quality of their elastic elements, in particular their endurance and resistance to the action of intense cyclic loads. For effective vibration isolation of the working body of a resonant vibrating machine from the frame, the suspensions must have sufficient softness, while increasing productivity requires the maximum possible rigidity of these elements.
The paper provides recommendations for the calculation and design of elastic suspensions of vibrating technological machines operating in both sub-resonant and resonant modes, as well as elastic elements with adjustable stiffness for machines with an adjustable electromechanical drive. Cylindrical helical compression springs are advisable to use in relatively small vibration installations with a container volume of up to 100 dm³, installing them without tilting. For more powerful machines, it is recommended to use combined suspensions or rubber-cord pneumatic cylinders placed at an angle to the longitudinal and transverse planes.
Of particular importance are resonant-type vibrating machines, which are distinguished by a number of technological, energy and operational advantages, but at the same time are characterized by the dependence of dynamic parameters on the degree of loading.
In view of this, a promising direction is the use of suspensions with adjustable stiffness, which ensure the stability of the dynamic mode of operation of the vibrating machine and allow it to be changed in accordance with a given algorithm. An effective solution is also combined elastic suspensions, which combine a diaphragm pneumatic drive with a rubber-metal block hinge. The torsional stiffness of such systems can be changed by adjusting the number of block hinges, and the stiffness of the diaphragm by changing the gas pressure in the suspension cavity.

Bernyk, proposed to create a professional all-Ukrainian scientific and technical journal "Vibration in engineering and technology..The journal was foundedat Vinnytsia State Agricultural Institute and P.S. Bernyk was elected to be the chief editor .
For all these years (since 1994) theJournal "vibration in engineering and technology" published 119 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
