“…The developments in the automotive industry within the last decades has demanded the actual vehicle designs to be innovative and robust (Kim et al, 2014) in order to achieve, among others, short product development period, very high safety standards of the body panels and the overall reduced weight (Park and Dang, 2011). Such vehicles require stronger and lighter materials (Bae and Huh, 2012;Cho et al, 2013).…”

In this paper the results of experimental tests aimed to determine the friction coefficient in sheet metal forming operations for various sheet metal materials and at different operative conditions are presented. The research has considered the frictional characterization of three kinds of drawing quality steels that are commonly used in automotive industry. These are a drawing quality steel (DQ), a deep drawing quality steel (DDQ), and extra deep drawing quality steel (EDDQ). For measurement of the sheet surface topography, a 3D stylus instrument Alicona InfiniteFocus was used. To determine the friction coefficient three tribological tests, i.e. a strip drawing test, a draw bead test and a pin-on-disc tribometer, have been conducted. The experimental results have ascertained several relationships showing the effect of sheet metal surface roughness, lubricant conditions and sheet orientation on the value of friction coefficient in sheet metal forming processes. The results further showed that the surface topography and sample orientation in the rolling direction of the sheet are significant factors that influence the friction coefficient. It was found that the tested steel sheets, selected from automotive industry applications, exhibit anisotropic resistance to the friction corresponding to the measured orientation in relation to the rolling direction of the sheet.

“…In this study, the optimization problem was solved by using a commercial design program (Easy Design V3R7, Optimal Design Incorporated, Korea). This design program is a commercial optimization tool that uses a sequential approximate optimization algorithm based on a progressive meta-model [16] . Table 8 presents the analysis conditions to find the optimal solution.…”

In this study, roller shape optimization was performed on a roller-type pot-seeding machine used for sowing onion seeds. The parameters for optimization were derived by analyzing the operating characteristics of the pot-seeding machine. Based on this, the roller shape was determined to minimize weight while satisfying the required strength. When the optimized roller shape was applied, it was possible to reduce the weight of the roller by 17.7% compared with the conventional one, while satisfying the safety factor of 2.0 or more. The optimum bed soil compaction required for onion sowing was also obtained. Therefore, applying the roller shape derived from this study to an existing roller-type pot-seeding machine may increase the production efficiency of healthy seedling.

“…These design problems usually have the typical characteristics of complexity and uncertainty. Many design approaches have been introduced to deal with such difficulties and some papers especially explained the vehicle and its parts design processes (Kim et al, 2014;Chen et al, 2015;Ma et al, 2013, Sahoo et al, 2015Yoon et al, 2013). The methodical design approach (MDA) has also been used to design engineering products recommending various special systematic methods for designers.…”

This paper describes the designing and manufacturing process of a complex special utility vehicle (SUV) using the methodical design approach for which the basics were explained decades ago in Germany. The application steps of the design methodology with comprehensive data are clearly outlined and the experiences gained during the project along with the authors' experiences in design research and design practice over 25 years are generously shared. This paper contributes to the methodical approach laid by Pahl & Beitz with an industrial example proving its applicability in real engineering design applications. The proposed solutions for difficulties encountered in the process are especially valuable and applicable for SMEs (small and medium-sized enterprises) in the field. Such details are reported with comprehensive discussions in this paper.
