【 摘 要 】

The purpose and objectives of the work are to develop scientific and technical bases and experimental testing of the dynamic method of control of the dynamic viscosity of liquids located directly in the pipeline on the basis of angular accelerations of the body immersed in the liquid. The developed method of control of the dynamic viscosity of liquids allows to take into account the uneven supply of mechanical energy from the drive motor of the rotary viscometer based on the assessment of the dynamics of the motion of the body immersed in the liquid. The developed method of control of dynamic viscosity of liquids is based on the proven positions of theoretical mechanics, dynamics of rotational motion, the theory of machine parts and is a logical continuation of the development of rotational methods of control of viscosity of liquids. The results of experimental testing of the developed dynamic method of control of the dynamic viscosity of liquids suggest the adequacy of the developed approaches. As a result of experimental studies of motor oil G-Energy 10w-60 on the basis of the developed dynamic method revealed the ratio of dynamic viscosities at temperatures of 100 ° C and 40 ° C, which was 6,7. Application of existing methods of control of viscosity of G-Energy oil at temperatures of 100 ° C and 40 ° C gives the ratio of dynamic viscosities 6,8. The discrepancy between the results of the dynamic method of control of the dynamic viscosity of the liquid and the control results obtained by known methods of control of the dynamic viscosity of liquids is about 1%.
