| چکیده | ||
| در این تحقیق با بکارگیری شیر کنترل الکترونیکی اتصال سه نقطه جدید، سامانه کنترل کشش الکتروهیدرولیکی طراحی، ساخت و بر روی تراکتور MF285 نصب گردید. اجزای سامانه الکتروهیدرولیکی شامل حسگر نیروی کشش، حسگر عمق شخم، PLC، موتور پله ای و درایور آن، شیر کنترل و صفحه نمایشگر می باشد. نتایج آزمایش های کارگاهی نشان داد که عملکرد سامانه در پاسخ به تغییرات پله ای نیروی کشش رضایت بخش بود و موقعیت گاوآهن متناسب با نیروی اندازه گیری شده تغییر داده شد. همچنین در زمان ثابت بودن نیرو، سامانه کنترل کاملا پایدار بود. نتایج مزرعه ای نیز نشان داد که در تمامی تیمارها بین میانگین درصد لغزش چرخ ها و مصرف سوخت دو سامانه اختلاف معنی داری وجود داشت(P<0.05). سامانه الکتروهیدرولیکی در مقایسه با سامانه هیدرومکانیکی در حداکثر سرعت پیشروی و حداکثر نیروی کشش تنظیمی، درصد لغزش و مصرف سوخت را به ترتیب 6/44 درصد و 3/29درصد کاهش داد. | ||

| چکیده [English] | ||
| In this research an electro- hydraulic system was designed, constructed and installed on the Massey Ferguson (MF) 285 tractor by using a new hitch control valve. The electro- hydraulic system consisted of a tensile load cell, a potentiometer, a PLC, stepper motor with driver, hitch control valve and a Programmable Terminal. The experiment results showed that the performance of the electro-hydraulic control system was satisfactory in response to the draft force variations and the position of plow was altered proportional with the draft force. Also the control system was stable when the draft force was kept in the constant value. The field results showed significant difference between two control systems in fuel consumption and wheel slip (P<0.05). The electro- hydraulic draft control system decreased the fuel consumption and slippage by 44.6% and 29.3% respectively at the maximum draft set value and ground speed, compared to the mechanical draft control system. | ||
