Kolot А. Scientific bases of increase of efficiency of the system of drives by the account of stochastic of their characteristics

The object of researches is system of drive gears of the diagnostic bench equipment. The purpose of work is increase of a system effectiveness of drive gears by the account of stochasticity of their characteristics. The methods of research is mathematical modelling with appli-cation of the COMPUTER, probability theory .In result of probes are developed scientific bases of increase of a system effectiveness of drive gears, the complex stochastic mathematical model dissipative an element of the drive gear (hydraulic shock absorber) which allows to define influence of separate parameters of the drive gear on the general processes of change and transformation of power in system of drive gears is developed. It is developed algorithmic program complex for imitating mathematical modelling system of drive gears of the bench equipment for diagnostic tests of hydraulic shock absorbers. It is developed, approved and introduced the bench equipment which allows to carry out diagnostic tests of a hydraulic shock absorber under laws which correspond to real operating conditions of the absorber while in service in Ukrzaliznyca.The field of using the railway transport.
