The main scientific directions of the department:
In chronological order, the department was the first to research on the use of ultrasound energy in the processes of abrasive lapping and finishing of various surfaces, including conical, spherical and flat. It was scientifically substantiated and experimentally confirmed that through the use of ultrasound it is possible to intensify, and most importantly, automate the process of joint abrasive grinding of conical surfaces. The use of ultrasound intensifies the process of stock removal and improves the quality of machined surfaces. On the basis of the research carried out, technological processes were developed and high-performance equipment was created for multi-place grinding with ultrasound of the conical surfaces of plug valves used in gas equipment systems.
On the basis of theoretical and experimental studies, a rational acoustic system was substantiated for finishing small-diameter balls with ultrasound. In comparison with traditional processing, the performance of finishing balls is increased by 3-4 times, the process of achieving the required surface roughness parameters is accelerated by 3-5 times. Its microhardness increases by 1.1–1.2 times, the depth of the hardened layer increases by 2–3 times, and the value of the breaking load increases by 20–25%. Based on the results of the research, a technological process for finishing small-diameter metal balls was developed and a pilot model of the VSh-D14 ultrasonic ball-bearing machine was created. A technological process for fine grinding of glass beads with ultrasound has been developed.
The second independent area of technological application of ultrasound is associated with the production of diamonds. In order to increase the yield of diamond suitable for sawing single crystals, a technology was developed and a pilot plant was created for superfinishing the side surfaces of sawing discs with ultrasound.
To intensify the process of turning diamond crystals, a technology was developed and ultrasonic hand tools and an ultrasonic spindle for the ShP 6 turning machine were created.
A number of interesting developments have resulted from fruitful cooperation with specialists in the field of medicine, some of which are already being used in clinical practice. These are 2 rehabilitation stands for stretching the spine and restoring the musculoskeletal system, a device for measuring the cervix of the uterus, which allows you to determine the exact date of delivery.
The department has developed devices that allow to destroy blood clots in blood vessels using ultrasound, to reduce the required dose of gamma irradiation in the treatment of cancer patients
Students take part in the scientific research of the department. Among the graduates of our department there are 2 Presidential scholarship holders (former students Sergey Karpovich and Yuriy Rozanov), a former postgraduate student Dmitry Stepanenko, now a professor of the department, received a Presidential grant. On average, every year more than one and a half hundred students of the department participate in scientific work, about fifty articles, abstracts of reports are published at international and republican conferences with the participation of students. Only in recent years, students of the department have filed more than 10 applications for inventions and utility models, a number of patents have already been received. Every year more than 10 students submit their works to the Republican competition of scientific works, most of them are awarded the 1st category.
Students who have the desire and ability to engage in scientific research can continue their education in the magistracy in the specialty: 7-05-0716-03 "Instrument Engineering" and postgraduate studies at the department in the specialtys: 05.11.01 «Devices and methods of measurement (measurement of mechanical quantities)», 05.11.14 «Instrument engineering technology», 05.11.17 «Devices, systems and products for medical purposes».
At the expense of talented youth, the department replenishes its teaching staff. In recent years, 5 candidate and 1 doctoral dissertations have been defended at the department.
