چکیده

هدف از این پژوهش نشان دادن مزایای شبیه سازی رایانه ای و مطالعات پارامتری در بهبود فرآیند الکتروفرمینگ مس می باشد. برای این منظور مدل المان محدود برای یک هندسه مخروطی شکل با استفاده از نرم افزار کامسول تهیه و اثر پارامترهای کلیدی شامل دانسیته ی جریان اعمالی، هدایت الکتریکی محلول، فاصله ی الکترودها، و طول آند، بر میزان یکنواختی ضخامت بررسی شد. به منظور صحت سنجی مدل، یک پوسته ی مخروطی شکل در آزمایشگاه به روش الکتروفرمینگ تولید، و توزیع ضخامت در آن با نتایج حاصل از شبیه سازی مقایسه شد. مقایسه ی نتایج نشان داد برای شبیه سازی فرآیند الکتروفرمینگ، استفاده از مدل توزیع جریان سه گانه ، یک مدل دقیق و کارآمد است و می توان از آن برای مطالعات پارامتری استفاده کرد. در نهایت پس از مطالعه ی پارامتری مشخص شد همه ی متغیرهای انتخاب شده تاثیر قابل توجهی بر ضخامت کلی ایجاد شده و میزان یکنواختی ضخامت دارند. علاوه بر این مشخص شد که دانسیته ی جریان اعمالی بیش ترین و فاصله ی الکترود ها کمترین اثر را بر مقدار ضخامت و یکنواختی آن دارد.

چکیده [English]

The purpose of this study is to demonstrate the advantages of computer simulation and parametric studies in improving the copper electroforming process. For this purpose, the finite element model for a cone geometry was prepared using the Comsol software, and the effect of key parameters including applied current density, solution electrical conductivity, electrode spacing, and anode length, on the thickness uniformity. In order to validate the model, a conical shell was produced in the laboratory by electroforming method, and the thickness distribution was compared with the simulation results. The comparison of the results showed that using the tertiary current distribution method to simulate the electroforming process is a precise and efficient model and can be used for parametric studies. Finally, after parametric study, it was determined that all selected variables had a significant effect on the thickness uniformity. In addition, it was found that the most to least significant variables were applied current density, solution conductivity, anode-cathode spacing, and anode length, respectively.
