Yangirov I. F., Khalikov A. R., Karamov D. M. � Magnetoelectric vibration sensor

The original design of the MVS with improved metrological characteristics, i.e. increased sensitivity and steepness of the conversion characteristic due to the additional execution of slits under the bevel in the Ministry of Internal Affairs is given. Analytical relations for the analysis and design of the MVS are derived, taking into account the bevel of the slots and experimental confirmation of the results obtained. Studies have shown that ways to increase the sensitivity and steepness of the transformational characteristics of vibration acceleration sensors play an important role in instrumentation and there is a need to study previously known and, based on the experience of their creation, explore new possible ways of design solutions.
Key words: vibration, sensitivity, magnetoelectric, ferromagnetic, permanent magne

In order to improve the technology of manufacturing spring materials, the technological possibilities of using preliminary thermomechanical treatment to obtain increased hardness and ductility of carbon steels have been studied. The fundamental possibility of hardening metals by the method of broadening extrusion, as well as with the use of subsequent heat treatment, is shown. The results obtained can be used in the production of spring materials and core parts (small tools, fasteners, etc.).

Golovkin P. A., Kryukov A. V. � The effect of pre-deformation on the structure of the material and the quality of the surface when turning steel 30KhGSA

The article shows that taking into account the successive impacts on the metal material during its various processing allows you to obtain high-quality parts with the specified balanced target and technological characteristics with minimal costs. The parameters of forging that provide a balanced set of parameters of workability by cutting, material quality and surface cleanliness of the machined workpieces made of 30XGSA steel are justified.
It is shown that forging makes it possible to neutralize such a feature of the original bars as the presence of an undesirable zone of breaking of the deformation rates formed during their rolling, and increases the uniformity of the material of the workpieces. In addition, the use of complex forging due to the uniform processing of the material of the workpieces provides a better quality of their surface during turning, stabilizes the load on the tool.

Moskvin V. K., Kuznetsov P. M., Feofanov A. N. � Improving the performance of the servo electro-hydraulic feed drive with an analog control system

The article deals with the issues of improving the performance of a servo electro-hydraulic feed drive with an analog control system, designed to be used as a drive for the gripping body of an industrial robot. As a result of the studies of the typical scheme, the main drawback was revealed � limited speed capabilities. In the process of finding a way out of this situation, a variant of the drive with feedback on the position of the damper was proposed.

Presented in the article are tomographic research results obtained for distribution of cladding mix components volume fractions in casting mold unit cells in the areas of silica sand sloughing during casting of blank for diesel engine cast-iron cylinder. X-raycomputational tomography was used to determine volume fractions of silica sand, phenolics and pores within the area of sand sloughing as well as to identify the main cause of sloughing. Given herein are tomograms obtained for cross-sections of diesel engine cast-iron cylinder blank with defective area occurred where silica sand mixed with cast iron during casting process.
