Authors: Shcherbakov Y. M , Frolov V. N
Published: April 2022

The authors propose a method for testing plastics endurance under plane transverse bending with a given cyclic deformation. The paper describes the relations for the calculation of the amount of deflection, rotation angles of the end parts of a sample and the technological gap d between the pins in movable supports and a model for the transverse bending of a sample, the properties of which are given by linear-elastic and nonlinear elastic (according to power law) models. To determine the dependence of stresses on the number of cycles before sample failure, the authors propose the method for estimating stress with the use of the dependence of stresses on the number of cycles before failure and stress-deformation dependence, obtained in quasi-static tests under "instantaneous" loading.

Study of mechanism of influence of internal air flows on overall vehicle aerodynamics
Authors: Petrov A. P
Published: April 2022

The article considers the problem associated with the influence of internal air flow on the aerodynamic drag coefficient of an automobile. The main part of the air flowing through the interior space of the car is used for blowing a cooling radiator, and at the same time aerodynamic resistance of the vehicle increases. The mechanism of this effect was investigated. It was found that the main factor is the interference of airflow flowing around the front part of the vehicle. It is caused by a decrease in the amount of air as the portion of air passes through the inside. Thus, the proportion of the aerodynamic drag associated with the airflow through the engine compartment depends on its flow rate.

Incremental geometrically nonlinear axisymmetric finite element model of forming process of thick sheet metals under the action of rigid tools
Authors: Sukhomlinov L. G , Mikhaylova V. L
Published: April 2022

An incremental rigid-plastic axisymmetric finite element model for the analysis of thick sheet metal forming processes under the action of rigid tools is developed on the basis of a triangular element with the linear law of displacements' distribution. The nonlinear effects due to the changes in sheet geometry and contact states during each incremental step are taken into account. Examples on drawing of thick metal sheets through conical and cylindrical dies are considered.

Investigation of the influence of the catalyst in the process of producing biodiesel using supercritical methanol
Authors: Sister V. G , Ivannikova E. M. , Kirshankova E. V.
Published: April 2022

The article discusses various ways to produce biodiesel fuel: in the presence of homogeneous catalysts, in the presence of heterogeneous catalysts, in supercritical methanol. There was experimentally confirmed that the process of obtaining methyl ethers of fatty acids (FAME) in the supercritical methanol on the selectivity, on replacement of the target product and process stability in time can compete with catalytic methods. There was studied the efficiency of the catalyst at the transesterification of rapeseed oil in supercritical methanol under the following process parameters: temperature of 300°C, the pressure of 300 atmospheres, the volume fraction of oil 0,5. There was evaluated that during the first hours after the filing of the reagents into the reactor in the presence of a catalyst TiO2/Ti concentration FAME in the oil layer of the reaction products is more than in not catalysed reaction. However, approximately one hour after the beginning of the process of catalytic activity was sharply reduced, and the output of the FAME becomes less, than without a catalyst. By means of mass-spectral analysis of the product, extracted from the surface of the catalyst, it is discovered a tumor in the process of interesterification low-volatile and poorly soluble substances, blocking the active centres of the catalyst. In addition, the reduction in catalytic activity became the result of partial destruction of the surface layer of TiO2. It is established, that the washing of the spent catalyst mixture of solvents with the subsequent heating at 350°C allows largely to restore the activity of the catalyst.

Study of vibration sensitivity of a rotor of stationary gas-turbine unit on slide bearings to change of main settings of the system
Authors: Temis Y. M , Temis M. Y , Egorov A. M
Published: April 2022

The results of the study of vibration sensitivity of a rotor of stationary gas-turbine unit (GTU) on slide bearings to the change of the main settings of the system are described in the paper. The authors used a beam model of the rotor which takes into account the non-linear stiffness and damping characteristics of an oil film in radial bearings, and a multi-disciplinary model of rotor dynamics including the model of the shaft, rotating discs and radial bearings. Numerical calculations for calculating the orbits of GTU rotor at different operating conditions are performed. The paper also demonstrates the sensitivity of the “rotor-bearing” system to a change of system parameters such as a disbalance of the rotor, constructive damping and viscosity of the oil in bearings.

Authors: Reformatorskaya I. I , Podobayev A. N , Shishlov D. S , Chibysheva V. D , Artamonov O. Y
Published: April 2022

The state of various areas of the surface of a test melt of carbon steel containing 0,2% of carbon and 0,75% of chrome was analyzed by means of methods of energy-dispersive analysis and scanning tunneling micro- and spectroscopy. Without corrosion-active sulfide inclusions, the local corrosion spots are inert chromium carbides and oxides of aluminum. Spots of localized corrosion occur in places where above mentioned carbides and oxides brake the surface due to accelerated etching of the metal/inclusion boundary, where are seen a rapid increase of the tunneling activity.
