Abstract

Relevance The development of new designs of electromechanical vibration transducers (EMVT) is an urgent task and is caused by the need to create devices that meet to one degree or another many, often contradictory requirements for accuracy and measurement limits, frequency range, sensitivity, overall dimensions, weight, cost, performance characteristics, etc. An important prerequisite for solving the set tasks is the study and development of new promising structural elements of electromechanical converters, materials, components, special production processes. The rapid development of science and technology causes a great variety and complexity of automatic control systems. Invariant, self-adjusting and other complex information-measuring and control systems are created, to which increased requirements are imposed. The modern development of automated monitoring and control systems for various technological and physical processes is characterized by the widespread use of primary means of collecting and processing information. At the same time, electromechanical vibration transducers EMVPsensors of vibration parameters are a link in any information-visual or control system and practically determine its metrological characteristics. Losses in the accuracy and reliability of the final result associated with unsuccessful use of the sensor cannot be restored by the most advanced information conversion system. The range of industrially produced vibration sensors is limited, and their effective operation and evaluation of experimental results is very difficult. The lack of clear recommendations for choosing one type of sensor or another, sound methods of engineering calculations and experimental studies, and analysis of limiting operational and technological capabilities has led to the fact that many types and designs of sensors turned out to be unviable. A large number of publications related to the design of new designs of vibration sensors for various purposes and the improvement of already known ones allows us to judge the continued interest of developers in this class of devices, especially with the development of technical robots and flexible modules. The lack of fundamental theory and engineering methods for calculating the static characteristics of electric motors in the mode of both a sensor and a motor with a spiral electrically conductive element limits the possibility of their rational design for information-measuring and control systems. Therefore, the tasks of researching and creating highly efficient EMVPs with a spiral secondary element that most fully satisfy the special requirements of control systems are relevant. Aim of research To investigate a vibration transducer (EMVT) with a closed spiral secondary element in the mode of generating low-frequency vibrations and improving mechanical data due to the execution of longitudinal slits with a bevel in a spiral electrically conductive spring. Research methods Literary review and patent study, methods of mathematical modeling and experimental studies of vibration oscillations. Results For the first time, a method and methodology have been developed for the design of electromechanical vibration converters with a spiral secondary element with theoretical and experimental confirmation of the main obtained positions. A full-scale sample with theoretical provisions was developed, a patent of the Russian Federation was obtained, the possibility of using a structural solution in household devices (tablets, laptops, electronic watches, nanorabototechnics, vascular medicine and cardiology, information transmission as GPS u GSM elements, etc.) was shown.
