چکیده | ||
این مقالۀ پژوهشی بهمنظور تعیین ضریب فنریّت و میرایی سیستم تعلیق کابین تراکتور ITM285 با هدف افزایش راحتی کاربر تراکتور انجام شد. تجزیه و تحلیلها باتوجه به میانگین مربع پاسخ شتاب در باند یکسوم اکتاو و سازمان بینالمللی استاندارد (ISO) انجام پذیرفت. بهینهسازی پارامترهای سیستم تعلیق با روش بهینهسازی ازدحام ذرات (PSO) روی مدل 2 درجۀ آزادی سیستم تعلیق کابین تراکتور در نرمافزار MatLab در محدودۀ فرکانسی از 1 تا 10 هرتز مدل انجام پذیرفت. مقادیر بهدستآمده برای C1 و C2، K1، و K2 بهترتیب (Ns/m) 943، (Ns/m)850، (N/m) 3927، و (N/m) 26199 هستند. پارامترهای بهینهسازیشده برای سیستم تعلیق کابین تراکتور باتوجه به ISO 2631-1985 نشان از کاهش 7/16، 1/10، 5/11، و 2/12 برای زمان صعود، زمان نشت، و بیشینۀ جهش در مقایسه با مقادیر قبلی سامانۀ تعلیق دارند. درنتیجه باعث کاهش میزان ارتعاش به بدن راننده و همچنین بهبود وضعیت او میشود. | ||

چکیده [English] | ||
In this paper a survey to determine the spring and damper settings of ITM285 tractor’s cabin which ensured optimal ride comfort of tractor operator was conducted. Analysis has been done in terms of root mean square acceleration response (RMSAR) in one-third-octave band and International Standard Organization (ISO). Optimization was performed using particle swarm optimization (PSO) method on a 2 DOF modeled in MatLab software for frequencies ranging from 1 to 10 Hz. Obtained results for C1, C2, K1 and K2 were 943 (Ns/m), 850 (Ns/m), 3927 (N/m) and 26199 (N/m), respectively. Modeling tractor cabin using optimized parameters according to ISO 2631-1985, showed 16.7, 10.1, 11.5 and 12.2 % reduction in rise time, peak time, settling time and max. overshoot of tractor cabin displacement. Therefore, transmitted vibration was reduced and also improve the ride comfort of the tractor operator. | ||
