Рассматривается возможность интенсификации процесса изготовления разнонаправленных внутренних винтовых пазов трубных корпусных деталей, используемых в судовых энергоустановках и пусковых устройствах для запуска подводных и летательных беспилотных аппаратов, и их элементов, испытывающих многократные нагрузки в период эксплуатации. Для выбора наиболее рационального и эффективного способа изготовления применен функционально-структурный анализ используемого оборудования для изготовления внутренних винтовых пазов трубных корпусных деталей, с помощью которого найдены закономерности процесса. Выявленный способ обработки, оборудования и применяемый инструмент являются наименее затратными и наиболее эффективными для выполнения необходимых технических требований. При проведении анализа зон локальных деформаций выявлен ряд зависимых величин, влияющих на конечное усилие и степень деформации при изготовлении разнонаправленных внутренних винтовых пазов трубных корпусных деталей. The possibility of intensification of the process of manufacturing of multi-directional internal twist grooves of tubular bodyparts used in ship power plants and launching devices for launch of underwater and aerial unmanned vehicles and their elements experiencing multiple loads during operation is considered. In order to select the most rational and efficient method of manufacturing, functional-structural analysis of used equipment for making internal twist grooves of tubular body parts is used, with the help of which process regularities are found. The identified method of processing, equipment and tool used are the least expensive and most effective to meet the required technical requirements. Analysis of local deformation zones revealed a number of dependent values affecting final force and degree of deformation during manufacture of differently directed internal twist grooves of tubular body parts.

The following analysis deal with the possibility of intensification for the manufacturing process of the multi-directional internal screws of the pipe hull parts, used in the ship power plants and launch devices to launch submarine and unmanned aerial vehicles as well as their elements ,which experience multiple loads during their period of operation. Functional-structural analysis of the equipment, used for the manufacturing of the internal screws of the pipe hull parts, has been applied in deciding the most rational and efficient way of production. This analysis helps to find process patterns. The revealed way of machining, used equipment and the applied instrument provide the least expensive and the most effective results to execute necessary technical requirements. During executing local deformation areas analysis, there have been revealed a number of dependent values which make an impact on the final force as well as the deformation degree when manufacturing multi-directional internal screws of the pipe hull parts.

Mounds, as anthropogenic constructions of a very delicate structure, are subdued to constant changes, which, due to the impact of external factors (prolonged precipitation, tremors) are subdued to deformations in the form of mass movements. These phenomena usually have the character of mild soil creep in time and sometimes, as a result of rapid loss of stability, they are seriously damaged by landslide. This phenomenon causes temporary exclusion of the object from use. In the framework of the protection of these objects, the maintenance was carried out within the preventive measures referring to the construction and surveying monitoring of the geometry changes in time, as a result of phenomena taking place in the ground medium under the influence of environmental factors causing strains. The process of the deformation of mounds is similar to the characteristic, according to the Terzagie's theory. The application of surveying technologies of high precision allows the monitoring of changes in their geometry in time. The properly defined study area and the proper selection of measurement technology in the aspect of the accuracy of the prediction of changes, can efficiently help in defining the scale of deformations in the decisive process referring to the way of efficient protection of barrows. The article presents the results of point monitoring carried out with surveying technologies within 11 measurement series carried out on the selected measurement base of the Wanda Mound. The use of measurement technologies of integrated and specialist software, allows complex assessment of the degree of deformation and the trends of these changes in time, as well as identifying anomaly zones in the framework of the landslide monitoring.
