Abstract [en]

Traditionally, design analysts are solely responsible for all computer-based design analysis (CBDA). CBDA refers to quantitative design analyses utilizing computational tools in the engineering design and development of technical solutions. There are currently limited insights into and knowledge of tools and methods needed to facilitate the use of CBDA by engineering designers. In order to gather information on this aspect of CBDA, an industry survey has been performed. 77 persons completed the survey (16% affiliated to NAFEMS) open for twelve weeks during October-December, 2014. Around 35% answered that within their companies CBDA is used by engineering designers, and 28% of those who are not currently doing so expect to do so in the future. Linear static analysis is the most frequent type of analysis performed by engineering designers. The benefits put forward by the respondents in favor of involving engineering designers in CBDA are: it allows early evaluation of concept candidates, shortens lead time, frees resources for the analysis department, and reduces costs. 26% of the respondents answered that there is resistance from the analysis department against allowing engineering designers to perform CBDA, 19% within the engineering design department are also against this involvement and 26% answered that there has been no problem associated with this involvement. Even though the engineering designer performs CBDA on his/her own, supervision (56%) and quality assurance of the analysis results (59%) is the responsibility of the design analysts. This is also the case regarding the development of tools and methods to be used by the engineering designers as well as instruction and training of the engineering designers.

Abstract [en]

The current trend in industry to encourage engineering designers to take an active part in the analysis of their own design solutions is apparent in many companies today, domestically as well as abroad.

From a research project with the objective to develop a computer-based design system for the design of lightweight grippers, one of the major difficulties was to overcome the system users’ lack of knowledge and experience in the design of lightweight structures and Computer-Based Design Analysis (CBDA). CBDA here refers to the use of analysis tools such as Finite Element Analysis (FEA) and computer-based structural optimization. In order to handle these difficulties, the author introduced the use of templates. In the given context, a template refers to an especially preformatted code, which contains the implemented information/knowledge necessary to perform a specific task on an operational level. It should be noted that the use of templates as a means of support in performing a specific design or analysis task is not a new phenomenon in industrial practice. Inspired by the opportunities provided by the template approach, the main objective set out for the thesis project was to facilitate the active participation of the engineering designers in performing CBDA singlehandedly, or in any other organizational setting, by utilizing a Template-Based Design Analysis (TBDA) approach, as an integrated part of their activities within the engineering design process.

The evolutionary research approach for the development of the TBDA approach is based on surveys in Swedish as well as international industry, literature surveys, the development of a Generic Design Analysis (GDA) process model (facilitating integration of the activities between CBDA and engineering design) and a number of demonstrator projects to deepen the insights into TBDA. Note that as the TBDA approach is intended for use in industrial practice, the approach is independent of specific engineering design and product development processes utilized in industry.

The conclusion of the thesis work clearly supports the claim that TBDA is not only a competitive approach to current alternatives in supporting the engineering designers performing CBDA, but also of a complementary nature providing functionality not included in the alternative approaches currently used in industrial practice.

Abstract [sv]

Vid framtagning av nya produkter måste man utgå ifrån de behov som den blivande kunden ställer i form av krav och önskemål på produkten för att den ska vara intressant att inhandla och använda. För att säkerställa att den blivande produkten har de egenskaper som efterfrågas, används idag omfattande simuleringar av den blivande produktens egenskaper. Simuleringar består i avancerade beräkningar med hjälp av dator. Genom att utföra dessa tidigt i utvecklingsarbetet, så kan man väsentligen korta ned tiden för utveckling och konstruktion av produkten. Detta uppnås framför allt genom att minska behovet av att bygga och prova prototyper. Beräkningar i utvecklings- och konstruktionsarbetet spelar därför idag en väsentlig roll för att ta fram konkurrenskraftiga produkter på ett snabbt och effektivt sätt.

I denna avhandling har ett nytt tillvägagångssätt tagits fram för att låta konstruktörer själva beräkna sina konstruktionsförslag. Hittills har merparten av alla beräkningar av detta slag genomförts av beräkningsingenjörer. Nu kan man genom att tillämpa den i avhandlingen framtagna tillvägagångssättet att med hjälp av digitala mallar (program för att lösa speciella uppgifter i konstruktionsarbetet) och det föreslagna tillvägagångssättet MallBaserad KonstruktionsAnalys (MBKA) tillåta att konstruktörer, som vanligtvis inte är specialister på beräkningar, självständigt kan utföra sådana analyser. Mallarnas roll är alltså att överbrygga brister i kompetens och erfarenheter av konstruktionsberäkningar.

Redan idag finns konkurrerande sätt att tillåta konstruktörer att delta i beräkningsarbetet, men då oftast med direkt stöd av en beräkningsingenjör och med tillgång till riktlinjer. Dessa kräver att konstruktören har en viss grundkompetens för att kunna följa och tillämpa dessa. MBKA ställer inte dessa krav på kompetens och insikter, vilket gör att den kan betraktas inte bara som en konkurrent till existerande tillvägagångssätt utan också erbjuda ett helt unikt och nytt stöd genom att inte kräva kunskaper och insikter om konstruktionsberäkningar.

Av de reaktioner som erhållits i intervjuer i svensk industri, så ter sig framtiden för MBKA som mycket lovande. Många företag funderar redan idag på att införa tillvägagångssättet. Innan så kan ske, måste dock MBKA utvecklas ytterligare, vilket är målet för den fortsatta forskningen.
