چکیده

در این تحقیق جهت شبیه‌سازی روش سرعت بازگشت آونگ روی خربزه، تجزیه و تحلیل عددی نیرومندی پیشنهاد شد. تغییر پارامترهای ضربه روی دو رقم خربزه (زرد ایوانکی و سوسکی سبز) و در پنج مرحله رسیدگی بررسی شد. نتایج نشان داد که سرعت بازگشت، ارتفاع بازگشت، ارتفاع نسبی بازگشت، زاویه بازگشت، انرژی بازگشت و ضریب پس‌جهش (نسبت سرعت) با رسیدگی خربزه افزایش و انرژی جذب شده کاهش یافت. تجزیه و تحلیل رگرسیون رابطه خطی با معنی‌داری بالایی بین پارامترهای ضربه و پنج مرحله رسیدگی را نشان داد. نتایج تجزیه و تحلیل در تشخیص رسیدگی و از این رو در طبقه‌بندی بلوغ خربزه امکان‌پذیر است.
