    摘要:

    應(yīng)用Pro/E軟件建立了4UX—550型馬鈴薯收獲機(jī)與東方紅200P型拖拉機(jī)懸掛機(jī)構(gòu)參數(shù)化模型，進(jìn)行了拖拉機(jī)懸掛機(jī)構(gòu)與馬鈴薯收獲機(jī)裝配。將裝配模型導(dǎo)入ADAMS中，建立了液壓提升回路系統(tǒng)模型，進(jìn)行了機(jī)械系統(tǒng)與液壓系統(tǒng)的耦合仿真。結(jié)果表明，液壓力驅(qū)動(dòng)懸掛機(jī)組提升工況下，上懸掛點(diǎn)垂直方向出現(xiàn)最大力的時(shí)間要比機(jī)械力驅(qū)動(dòng)滯后0.080s，下懸掛點(diǎn)滯后0.088s；下降工況下，上懸掛點(diǎn)滯后0.056s，下懸掛點(diǎn)滯后0.060s。液壓力驅(qū)動(dòng)與機(jī)械力驅(qū)動(dòng)上、下懸掛點(diǎn)的受力基本相同，液壓缸緩沖力的波動(dòng)范圍為5.09～15.39N。

    Abstract:

    The parametric model of 4UX—550 potato harvester and suspension device of Dongfanghong—200P tractor were established with Pro/E software, and the assembly of suspension device of tractor and potato harvester was accomplished. The assembly model was imported into ADAMS. The hydraulic lifting loop system model was established. Then, the coupling simulation of mechanical system and hydraulic system were advanced. The results showed that when hydraulic pressure drived suspension unit, top hanging point appearing the biggest force evenly delayed 0.080s than that of the mechanical force driving, and lower hanging point delayed 0.088s under lifting conditions; top hanging point delayed 0.056s and lower hanging point delayed 0.060s under dropping conditions. When top and lower suspension points at the same force under the drive by hydraulic pressure and mechanical, hydraulic cylinder buffer force was in the ranges of 5.09~15.39N.
