ABSTRACT

Two control modes of technological equipment for ultrasonic welding of polymers are consi­dered: a mode with support of constant time and a mode of support of constant energy during the operation of the ultrasonic generator. The advantages of operation of the oscillating system in the constant energy maintenance mode are shown. A stand for modeling welding processes was developed and manufactured. An example of technological equipment that was manufactured based on the results of simulation of welding modes is presented.

KEYWORDS

ultrasonic welding, oscillating system, ultrasonic generator, PLL scheme.

ABSTRACT

The current state of machines with CNC (computer numerical control) and the problems that arise when using them are considered. The existing solutions to problems are described, and a new way of protecting machine components from breakdowns is proposed. Protection is based on the use of piezoelectric force and acceleration sensors. Additional protection can be implemented with the help of software in the CNC device.

KEYWORDS

ABSTRACT

An analysis of the platforms of information and control systems (ICS), the impact of the features of SMR projects on the digital infrastructure (DIS) comprising a complex of ICSs for various purposes, monitoring systems, and physical security. Structure of modern SMR DIS is suggested. The requirements for DISs/ICSs in view of these features, as well as the tasks that must be solved by DIS/ICS providers in order to realize the benefits of SMR are formulated.

ABSTRACT

The main areas of use of virtual conferences are defined in the study. The analysis of software development tools for conducting virtual conferences was performed. An analysis of the tasks was carried out, which helps to effectively solve the virtual conference. Each stage of conducting a virtual conference has been studied and described. The advantages and disadvantages of holding the conference are determined. A site for virtual conferences has been designed and software implemented, provided that all necessary conditions are met and potential shortcomings are eliminated. Software development technologies are considered. It is substantiated that the software development method for conducting virtual conferences includes three main stages: problem analysis and task setting; study of the theoretical foundations of software development for conducting virtual conferences; development and implementation of software for conducting virtual conferences. The basic processes of software creation have been studied. It is proven that the development of requirements is a process that includes the activities necessary for the creation and assertion of a document containing the specification of system requirements. An analysis of the levels of their detail was carried out: requirements put forward by end users; system specification for developers. Four main stages of the requirements development process were studied: analysis of the technical feasibility of creating a system; formation and analysis of requirements; specification of requirements and creation of relevant documentation; certification of these requirements. The main stages of creating a modern website are considered. The result of the requirements definition process is documentation that formalizes the requirements for the system. The developed site for holding conferences must meet the requirements of standards that regulate the life cycle of software. The fundamental processes characteristic of any software creation project are analyzed.
