چکیده-پخش بار بهینه به عنوان یکی از ابزار زیر بنایی برای تحلیل سیستم های قدرت پیچیده ،برای مدت طولانی مورد بررسی قرار گرفته است.پخش بار بهینه توابع هدف یک سیستم قدرت از جمله تابع هزینه سوخت ،آلودگی ،تلفات را بهینه می کند،و هم زمان قیود سیستم قدرت را نیز برآورده می کند.در کلی ترین حالتopf یک مساله بهینه سازی غیر خطی ،غیر محدب،مقیاس بزرگ،و ایستا می باشد که می تواند شامل متغیرهای کنترلی پیوسته و گ...
A Study on the Forming of Sheet Metal Parts Using Multi-Point Forming Technology
In recent years, in order to reducing die design and manufacturing costs, Multi point forming technique has gained an increasing interest because of its high flexibility. In this process, the conventional fixed shape solid die sets are replaced with a pair of opposite matrices of controllable elements. In this paper, the fundamental principles of multi-point forming was described and the possib...

متن کاملPhotogrammetric Measurement Techniques for Quality Control in Sheet Metal Forming
Within the Brite/EuRam project “DIGIMAN” a new optical measuring system for the assessment of sheet metal components in terms of shape accuracy and strain distribution has been developed. Based on the photogrammetrically measured geometric parameters of the object the system detects deviations from the desired geometry caused by springback and allows the strain analysis within critical stamping...
متن کاملOptimization of Process Parameters in Sheet Metal Forming
Figure 1 shows a simplified CAD representation of the tools and initial blank in the stamping process. During stamping, the metal sheet is submitted to large displacements and large elasto-plastic strains; rupture and wrinkles must be avoided, (Figures 2 and 3). The resulting part must also satisfy quality requirements regarding its geometry: after tools removing, the springback effect (Figure ...
