ENGINEERING PROJECTS FOR CONSTRUCTION OR RECONSTRUCTION OF INDUSTRIAL ENTERPRISES
- AUTHOR(S):

- ABSTRACT:
One of the important tasks of industrial design is the creation of engineering projects for the construction of new or reconstruction of existing industrial production processes and enterprises. The developed projects must meet certain conditions and a number of engineering and technical requirements in order to ensure high technical and economic indicators of the industrial enterprises. The aim of this paper is to specify some of the important characteristics of engineering projects for the industrial design of production processes and to propose a model for the technological design process, as this will systematize the steps and sequence in the process, as well as significantly facilitate any practitioner in this field. To achieve the goal, the comparative analysis method was used, comparing the types of possible engineering projects, on the basis of which the author developed the model proposed in the paper. The limitations in the study are reduced to the fact that the author himself sets the boundaries of his research and chooses only engineering projects, since project management is a vast scientific territory, and the volume of a scientific paper is too short. The topic is well known and still relevant because engineering project management is a daily activity for management specialists, but unfortunately there is still much to add and improve in the knowledge, skills and competencies of managers. Overall, the author believes that this is a topic that would help to achieve higher goals and results, and to improve the existing management practice.

DYNAMIC ANALYSIS AND CONTROL OF MODULAR UNIVERSAL ROTARY WELDING DEVICE
- AUTHOR(S):
Y. Kuznetsov, N. Pidhornyi
- ABSTRACT:
The article considers dynamic modeling and design features of a universal rotary welding device adapted to the needs of modern production. A modular construction principle is described, which allows to increase the functional flexibility and maintainability of the system. Based on the Lagrangian approach, the equations of motion for the rotary and tilting components of the mechanism are formulated, taking into account the action of external loads, damping forces and moments of inertia. Control options are analyzed, in particular the use of PID and adaptive controllers, which allow to ensure high positioning accuracy and reduce vibrations during operation.

- AUTHOR(S):
V. R. Kryvosheia, Y. M. Kuznetsov
- ABSTRACT:
The article considers the concept of a hybrid mobile robot that combines the capabilities of a walking platform and a quadcopter. The proposed system provides effective adaptation to complex terrain and the ability to switch to air mode to overcome obstacles. The design features, control algorithms, and energy consumption optimization are analyzed. Potential areas of application include rescue operations, military reconnaissance, and exploration of hard-to-reach areas.

- ABSTRACT:
In this work the results from electron-beam welding of copper and Al6082T6 aluminum alloy are presented. The different technologies for sample preparation and process conditions were applied to achieve strong connection between these two dissimilar materials. The influence of the filler presence on the structure and mechanical properties of the welded joint is studied in comparison with these without filler. The X-ray diffraction (XRD) method was used to obtain the phase composition of the welded joints. Scanning electron microscopy (SEM) was used for the study of the microstructure of the welds. The mechanical properties were studied and proved by means of micro-hardness measurements and tensile tests.
