PENETRATION DEPTH IN LASER MARKING OF COMPOSITE MATERIALS WITH TEXTILE REINFORCEMENT PHASE
- AUTHOR(S):
Simeon Tsenkulovski
- ABSTRACT:
This publication investigates the influence of the technological parameters of the laser marking process on the penetration depth of the laser beam in composite materials based on phenolic laminate with a textile reinforcing phase. Studies was conducted at the output power of the laser radiation - P=5÷50 W, marking speed - V=50mm/s and pulse frequency - f=50Hz. A graphical dependence of the obtained experimental results in comparison with the theoretical values is presented.

PROCESS MANAGEMENT IN ENGINEERING PROJECT PLANNING

- ABSTRACT:
The planning process group consists of those processes performed to establish the overall scope of the activity, define and refine objectives, and develop an action plan necessary to achieve those objectives. The planning processes build the engineering project management plan and documentation that will be used to implement it. The purpose of this report is to systematize and summarize the groups of processes necessary for the successful implementation of engineering projects, in order to make their implementation and adaptation easier in practice, which will significantly support the work of specialists in the planning and organization of engineering activities in industrial enterprises. The author makes no claims to exhaustiveness, as well as to the mandatory and literal application of the topic discussed in the practice of industrial processes. To achieve the goal, the methodology of system-structural analysis was used, which creates the opportunity to consider related processes and phenomena as a structured system that functions at the level of the industrial enterprise. One of the serious limitations that the author finds is that there is almost no research and there is a serious lack of scientific literature on the problems and issues related to project planning processes, and in particular, on planning engineering projects in industrial enterprises.

PROCESS MANAGEMENT IN ENGINEERING PROJECT PLANNING
- TITLE:
ENGINEERING PROJECTS FOR CONSTRUCTION OR RECONSTRUCTION OF INDUSTRIAL ENTERPRISES
- AUTHOR(S):
Tsanka Zlateva-Petkova
- 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.

- 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.
