DfAM: Application of the design rules in the early design stages
(Elsevier BV, 2023)
Djokikj, Jelena
;
With the rapid development of the additive manufacturing (AM) technologies the need for design methodology is also increased. Proper rules and guidelines in the early design stages can save time and ensure better end results. Main goal is to influence the designers and engineers to change their designing process by applying these rules and guidelines from the beginning of the process. In our research we are focused on the FFF (fused filament fabrication) as one of the most used AM processes by the designers and also engineers in the early product development stages. We apply the DfAM in different product designs in order to validate our premise.

DfAM: development of design rules for FFF
(Elsevier BV, 2022)
Djokikj, Jelena
;
The Additive Manufacturing (AM) technologies have huge advancement since their appearance in the late 90ties. The popularization of AM is due to their unique characteristics enabled by their specific working manner. The specific working manner requires new methodologies and approaches in the design process. With this paper we make contribution in that area. We are proposing a methodology for development of design rules for working with fused filament fabrication (FFF) process. Additionally we developed a set of design rules for designing and preparing for fabrication with FFF.

Индустрискиот дизајн, предизвици, развој, образование и апликативна дејност

Во периодот 2003-2005 година Универзитетот „Св. Кирил и Методиј“ ги прифати болоњските принципи за препознатливост на студиските степени, го воведе додатокот на диплома, го воведе кредит-трансфер системот, се зафати со развојот на постапки и системи за обезбедување на квалитет и оценка на квалитетот во високото образование и ги дефинира определбите за воведување и развој на доживотно учење. Во рамките на универзитетските реформи и Машинскиот факултет во Скопје претрпе промени на наставните програми, при што се воведоа, меѓу другите, и додипломски тригодишни професионални студии по индустриски дизајн. Од друга страна, во периодот на транзицијата на македонското стопанство од планска кон пазарна економија се реструктурираа старите претпријатија и се отворија нови, што резултираше со постепена ревитализација на производните процеси во различни сектори. Новите производи се карактеризираат со подобар дизајн и квалитет и можат да ги привлечат и домашните потрошувачи и потрошувачите од ЕУ. Токму поради тоа, студиите по индустриски дизајн се во моментов меѓу најбараните и најселектираните студиски програми на Машинскиот факултет во Скопје. Со цел да се излезе во пресрет на потребите на овој нов профил, во декември 2006 година беше пријавен Tempus JEP_41128_2006 проектот „Развој на магистерски студии по индустриски дизајн и маркетинг“, кој е прифатен во јули 2007. Согласно активностите предвидени со овој проект, подготвени се студиските програми за двегодишни магистерски студии по индустриски дизајн и маркетинг, како и програми за доживотно учење, кои започнаа да се изведуваат во учебната 2008/2009 година. Со воведувањето на магистерските студии по индустриски дизајн и маркетинг се комплетираа студиите во две нивоа, односно новите магистерски студии (второ ново) се надоврзаа на постојните тригодишни додипломски студии (прво ново) по индустриски дизајн на Машинскиот факултет во Скопје при Универзитетот „Св. Кирил и Методиј“ во Скопје.

Comfort analysis of vehicle driver’s seat through simulation of the sitting process
(Josip Juraj Strossmayer University of Osijek, Slavonski Brod, Croatia, 2014-04)
;
;
In this paper, a method for ergonomic analysis of the seating comfort in the driver’s seat for passenger vehicles is presented in two phases. In the first phase, the comfort seating postures of the driver are analyzed considering the comfort angles for the placement of human body and the necessary space for foot controls in vehicles, as well as the ranges of adjustments of the driver's seat and steering wheel. According to the determined comfort postures, the seat-human body virtual system is modeled. In the second phase, virtual testing of the seating comfort is performed with two different body sizes for 50th and 80th percentiles of virtual mannequins. The results can be used further to improve the arrangement of the basic comfort components for the driver's seat in vehicles. Virtual solid model of driver's body and driver's seat was created, especially for analysis of the pressure distribution on the contact surface of the virtual human body and the seat cushion foam. Virtual testing was performed using software package ABAQUS, simulating processes with finite element analysis method (FEA). The testing includes variation of the spatial mechanical properties of polyurethane foam and variation of the male body sizes for 50th and 80th percentiles. The results from the virtual testing were verified experimentally using pressure distribution mapping sensors. Using the virtual testing system for seating comfort, design changes of the seat can be introduced and verified.

Automating non-destructive product disassembly sequence generation
(Yıldız Technical University of Istanbul, 2015-05)
;
;
Remon Pop-Iliev
This paper focuses on presenting a newly developed product design software tool, referred to as ''OPTIDIS'', that is intended for effectivelly generating, evaluating, and optimizng customized non-destructive product disassembly sequences. The main advantages of this Concurrent Engineering tool include the ability to predict, evaluate, and define optimal disassembly sequences as early as possible into the product design stage while keeping the cost of disassembly operations as low as possible. In this context, ''OPTIDIS'' can be utilized to increase the percentage of reuse of components and material recycling, reduce their adverse impact on the environment, ease the servicing of products, and secure a greater total return from the end-of-life products. In essense, this enginering tool is capable of integrating the three-dimensional CAD (Computer Aided Design) solid model information that exists for a conceptual design solution for a given technical device with the established constraints regarding its assembly. Consequently, product design engineers can thereby obtain valuable insights and effective means for optimizing product’s disassembly sequences at a very early stage of the design process.

А method for improving the process and cost of non-destructive disassembly
(Transactions of the ASME, Journal of Mechanical Design, 2016-12)
;
Remon Pop-Iliev
;
The ever-increasing global environmental concerns demand that strong emphasis be given to the decision-making process pertaining to the strategy of design for nondestructive disassembly during the product evaluation stage. The ultimate objective is to considerably increase the percentage of product components and materials suitable for recycling, recovery, and/or reuse. In this context, this paper proposes a method for improving the nondestructive disassembly of a final product. This method analyzes the nondestructive disassembly by determining a disassembly interference matrix, feasible disassembly sequences, and improved nondestructive disassembly sequences. The innovative element of the nondestructive disassembly method proposed in this paper is integrating the generated conceptual design solutions for a given technical device with a software package developed for determining its improved disassembly sequence embedded within a 3D CAD platform. The developed procedure is based on information obtained from a 3D CAD model of a product, such as geometric constraints, automatic identification of fasteners and components, determination of component-to-component and component-to-fastener connection graphs, and AND/OR logic operations. The goal is for product designers to predict, evaluate, and define improved disassembly sequences while minimizing the cost of disassembly operations as early in the design stage as possible after a CAD model of the product becomes available. The applicability of the integrated method for determining the improved disassembly sequence is presented through an illustrative example.
