| چکیده | ||
| در این تحقیق، مقاومت کششی مورد نیاز، سطح مقطع شیار ایجاد شده، مقاومت کششی ویژه، مصرف سوخت تراکتور، لغزش، قدرت مالبندی، بازده کششی و بازده کل انرژی به هنگام زیرشکنی بررسی شده است. اثر سرعت پیشروی در چهار سطح 8/1، 3/2، 9/2 و 5/3 کیلومتر بر ساعت و عمق خاکورزی در دو سطح 40 و 50 سانتیمتر بر پایۀ طرح بلوکهای کاملاً تصادفی روی پارامترهای فوق مطالعه و این نتیجه به دست آمد که سرعت پیشروی وقتی افزایش یابد، مقاومت کششی، مقاومت کششی ویژه، مصرف سوخت، لغزش، قدرت مالبندی و بازده کل انرژی به ترتیب و به طور میانگین به میزان 7، 4/15، 10، 9/2، 3/108 و 6 درصد افزایش اما سطح مقطع شیار و بازده کششی به میزان 2/7 و 10 درصد کاهش مییابد. با افزایش عمق خاکورزی از 40 به 50 سانتیمتر، مقاومت کششی مورد نیاز، سطح مقطع شیار، مصرف سوخت، لغزش و قدرت مالبندی به ترتیب حدود 3/21، 6/25، 6/39، 8/2 و 4/21 درصد افزایش اما مقاومت کششی ویژه، بازده کششی و بازده کل انرژی به ترتیب حدود 4/3، 7/6 و 4/1 درصد کاهش می یابد. مناسبترین تیمار برای صرفه جویی در مصرف انرژی، عمق خاکورزی 40 سانتیمتر و سرعت 9/2 کیلومتر بر ساعت است. | ||

| Effect of Forward Speed and Tillage Depth on Tractor-Subsoiler Performance | ||
| چکیده [English] | ||
| The current research investigated the draft force, soil disturbance area, specific draft, tractor fuel consumption, slippage of drive wheels, drawbar power, traction efficiency, and overall energy efficiency of subsoiling. The effects of forward speed (1.8, 2.3, 2.9 and 3.5 km/h) and depth (40 and 50 cm) on these parameters were evaluated using a randomized complete block design. An increase in forward speed increased draft force by 7%, specific draft by 15.4%, fuel consumption by 10%, wheel slippage by 2.9%, drawbar power by 108.3%, and overall energy efficiency by 6% and decreased soil disturbance area by 7.2% and traction efficiency 10%. Increasing the subsoiling depth increased the draft force by 21.3%, soil disturbance area by 25.6%, fuel consumption by 39.6%, wheel slippage by 2.8%, and drawbar power by 21.4% and decreased specific draft by 3.4%, traction efficiency by 6.7%, and overall energy efficiency by 1.4%. The most efficient operating settings were a working depth of 40 cm with a forward speed of 2.9 km/h. | ||
