Shargorodskiy Sergey – PhD, Associate Professor of the Department "Machinery and Equipment of Agricultural Production" of the Vinnytsia National Agrarian University (3, Solnychna str., Vinnytsia, Ukraine, 21008, e-mail: sergey20@vsau.vin.ua).

The use of new energy-saving technologies has led to the significant development of vibration machine designs and their widespread use. In the course of their operation, the question of efficiency and reliability of the use of this type of machines is rather acute, related to the availability and possibility of using reserves of its operation.
Machines of this type must meet the requirements of quality and reliability in order to fulfill their official purpose. Due to the design features and the complexity of the processes occurring during their work, analytical calculations of durability and reliability in the classical version are quite approximate in nature and do not provide the necessary accuracy.
So the question of reliability and durability of vibrating equipment is urgent.
The questions of reliability estimation of vibrating machines were dealt with by the following scientists: Iskovich-Lototsky RD, Obertyukh R., Sevastyanov IV, Kanarchuk VE, Dzhratratano D.J. etc. The techniques they offer are virtually indistinguishable from those adopted in general engineering.
The publication proposes a technique for evaluating efficiency and reliability based on the use of quantitative characteristics of probabilistic and statistical nature. Such indicators for quantifying the reliability and reliability are: probability of failure, failure rate, failure rate, failure time. These indicators are one of the most important in the technical diagnostics of the operation of vibrating machines and the estimation of their residual life. The basic calculation, dependencies, analysis of laws are given.
