摘要
应用Pro/E软件建立了4UX-550型马铃薯收获机与东方红200P型拖拉机悬挂机构参数化模型,进行了拖拉机悬挂机构与马铃薯收获机装配。将装配模型导入ADAMS中,建立了液压提升回路系统模型,进行了机械系统与液压系统的耦合仿真。结果表明,液压力驱动悬挂机组提升工况下,上悬挂点垂直方向出现最大力的时间要比机械力驱动滞后0.080 s,下悬挂点滞后0.088 s;下降工况下,上悬挂点滞后0.056 s,下悬挂点滞后0.060 s。液压力驱动与机械力驱动上、下悬挂点的受力基本相同,液压缸缓冲力的波动范围为5.09～15.39 N。
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 0.080 s than that of the mechanical force driving,and lower hanging point delayed 0.088 s under lifting conditions;top hanging point delayed 0.056 s and lower hanging point delayed 0.060 s 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 5.09～15.39 N.
