چکیده
هدف تحقیق شبیه‌سازی بیومکانیکی پای ورزشکار و منسوج فشاری جهت اندازه‌گیری فشار اعمالی ساق‌بند فشاری بر پای جوان ورزشکار در جهت اعمال فشار بهینه و یکنواخت‌تر با تأمین حس راحتی بیشتر، هنگام پوشیدن بود. درروش تن‌سنجی مشخصات هندسی به‌دست‌آمده از تصاویر سیتی اسکن پای ورزشکار ورودی باکس نرم‌افزاری کد نویسی شده و با استفاده از نرم‌افزار پردازش مدل سه‌بعدی اولیه و مونتاژ عضو انجام شد. خواص مکانیکی پارچه فشاری ساق‌بند که از آزمایش‌ها تجربی اندازه‌گیری شده به باکس نرم‌افزاری وارد و عملیات شبیه‌سازی پوشیدن ساق‌پوش توسط نرم‌افزار آباکوس و بر اساس تکنیک المان محدود شبیه‌سازی شد. نتایج اندازه‌گیری فشار اندازه‌گیری شده بر پای داوطلب جوان ورزشکار توسط دستگاه کیکوهیم اندازه‌گیری و مقایسه گردید. نتایج حاصل از مقایسه مقادیر فشار اعمالی توسط ساق‌بند در حالت اندازه‌گیری شده و شبیه‌سازی بیانگر خطای بیشینه 44/ 14 درصد، مربوط به مقطع زیر زانو و نقطه پشت پا بوده و کمینه خطا 8 درصد مربوط به مقطع مچ پا و نقطه جلو پا است که باوجود فرضیات و منابع خطا در این شبیه‌سازی نتایج بیانگر دقت قابل‌قبول مقادیر فشار اندازه‌گیری شده در حالت شبیه‌سازی باحالت اندازه‌گیری شده است.

چکیده English

The purpose of this article is to biomechanically simulate athlete's leg and compression garment to measure the pressure on a young athlete's leg in order to apply more optimal and uniform pressure distribution while providing a greater sense of comfort when wearing.

The body condition and body shape of the athlete are measured by anthropometric method. Although Using a CT scan of the athlete's body (athlete's limb) and the mechanical properties of the pressure garment (leggings) that made of elastane spacer fabric was simulated by finite element technique. The results of measuring the real pressure on the young athlete's foot were measured and compared by a kikuhime device. The values of pressure applied by the leg in the real state and simulation indicate a maximum error of 14/44 percent (Cross section below the knee and the point behind the leg), a minimum error of 8 percent (Cross section of the ankle and the front point of the leg). Despite the assumptions and sources of error in this simulation, the results show that measured pressure values in the simulation mode with the real mode with incredible accuracy
