Study of Gaseous Flows in Closed Area With Forced Ventilation

Abstract

This paper deals with a design and a shape optimization of a tool that combines punching of a tarpaulin with the tarpaulin grommet pressing in one operation. The tarpaulin grommet 0.5 mm thick with a diameter of 10 mm is made of DX51D+Z275MAC steel. The designed tool and its main shape dimensions are verified by using a numerical simulation in an ANSYS Workbench software and subsequently also by a practical experiment, i.e. verification and debugging functionality in cooperation with H + D kovo company.

Enhancing Efficiency by Implementation of Integrated Management System in Order to Align Organisational Culture and Daily Practice

“…The results can be useful in the development of long-term sustainable PLM models [27,28,29]. The aim of the work is to improve the methods of processing and using technical and economic information in the design of complex products based on structural-parametric models, which take into account the possibilities for increasing the efficiency of use of resources and energy [30,31,32,33], as well as the development of sustainable infrastructure of processes at the stages of the life cycle [34,35,36,37].…”

Implementation of Integrated Management System in Order to Enhance Equipment Efficiency

“…In order to evaluate process parameters, Balara et al [1] developed signal processing procedure. Hang Wang & Jun Zheng [5] and Su & Jing Li [19] analysed technical details of virtual interface management, Militaru et al [12] reported methodology of software environment audits, Rimar et al [18] developed methodology of interaction analysis of the technical systems and environmental conditions. Todic et al [20], Durdan et al [4] and Krenicky [11] implemented multifactorial monitoring methods for evaluation of complex variation of characteristics.…”

“…An even more difficult situation is when a single system of standards is already implemented in the organization and is functioning successfully and the moment when the consumer demands from his supplier the introduction of a quality management system according to the industry standard (for example, ISO/TS 22163:2017 [9]). Thus, there is a contradiction between the need for the development of integrated models that allow for the analysis of dynamic evolutionary processes occurring at the interval of the product lifecycle management (PLM) [1,16,18] of sophisticated products, and the insufficiency of the existing regulatory and methodological support for the synthesis of such models in order to manage these processes. The solution to this problem is proposed to be sought in the creation and use of logical system-wide evolutionary models that must take into account the dynamic, parametric, economic, energy and operational processes occurring in each particular complex technical system [5,10,12].…”

Gas Flow Simulation in the Working Gap of Impulse Gas-Barrier Face Seal

“…However, as shown by recent experimental studies [2,4,5,16], the efficiency and the seal reliability can be significantly increased by changing the number of chambers and feeders, i.e. by changing the inter-chamber spaces [28,30,31,32]. Thus, in order to create more perfect seals, it is necessary to take into account the pressure unevenness factor in the circumferential direction, i.e.…”
