This study examined how the embossing effect of electroactive polyvinylchloride (PVC) gel, an electrically responsive material that changes shape under electrical stimulation, can be simulated in CLO3D and applied to shape-changing garment design. Three simulation approaches were developed based on the deformation characteristics of the electroactive PVC gel: pressure, warp and weft shrinkage, and elastic band strength adjustments. The visual similarity of each simulation approach and the actual deformation behavior of the gel were comparedusing experte valuations. The results demonstrated that the warp and weft shrinkage adjustment method most closely reproduced the embossing effect of the gel. Simulation settings with a shrinkage rate of 130% or lower and a pattern size of 3 inches or smaller yielded the most stable and aesthetically effective outcomes. Using these optimal conditions, three skirt designs (basicfitted, flare, and asymmetric) were proposed to verify the practical applicability of this embossing effect in garment design. By presenting a digital simulation-based method for reviewing designs that incorporate electroactive materials, these findings suggest practical design strategies for smart textiles and interactive fashion. This study also indicates the need for future research to extend this approach to a broader range of garment items and integrate user experience-based evaluations.
The functional wood plastic composite(WPC) is one of the noted materials for landscape architecture and residential construction. Iron band, embossing and drain holes are improve the strength and skid resistance of the WPC. In this study, we had developed an automatic manufacturing system for the functional WPC that has vertical pattern embossing and drain holes. The system is consist of an automatic vertical pattern embossing device, multi-spindle drilling M/C, sanding device, inspection equipment, and some facilities developed in the previous research. The performance tests on the several functional items of the system and manufactured WPC represented satisfactory values except the skid resistance and absorption thickness expansion rate.
A new plate heat exchanger for water-refrigeration systems such as chillers has been developed. Before forming, two stainless steel plates are placed on each other and connected by tig welding. To outline of the plate did the seam welding, in order to form the flow pass on the plate inside the spot welding used. After the plates have been welded, the plates are hydraulically inflated using pressure by water or nitrogen.The plate is made of an SUS plate of 1m×2m in length and 1.2mm in thickness and are fixed in the top of the water tank.As a result of these, it is concluded that the plate exhibits good cooling performance and the average cooling capacity is approximately 2.9RT/plate and the average coefficient of performance (COP) of chiller system is 3.16.
Based on the study of considering thickness and diameter of the panel it was found that bigger the diameter of panel more efficient for support the water pressure and less displacement. It was found that rise depth had little influence for stress and displacement at small embossed panel. Also the biggest stress occured along the side of the embossed panel.
