    摘要:

    對(duì)某小型玉米收獲機(jī)的整車性能進(jìn)行了研究,。將在Pro/E中建立的整機(jī)三維模型導(dǎo)入U(xiǎn)G中進(jìn)行了布爾和運(yùn)算,，減少約束,，簡(jiǎn)化模型,。運(yùn)用ADAMS建立了虛擬樣機(jī)模型，通過平路上的實(shí)車試驗(yàn)驗(yàn)證了所建仿真模型滿足虛擬試驗(yàn)要求,。利用虛擬樣機(jī)模型測(cè)試了整機(jī)的臨界側(cè)傾角度和最大爬坡坡度，從而避免了在危險(xiǎn)條件下的實(shí)車試驗(yàn)。同時(shí)利用虛擬樣機(jī)模型和車輛圓錐指數(shù)分析了機(jī)器在松軟地面上的通過性能,。

    Abstract:

    The performance simulation of a small-scale corn harvester for hilly area using ADAMS was presented. The 3-D parametric model of the corn harvester was established with Pro/E. Then, the model was put into UG to conduct Boolean operation to reduce the amount of constrains. Consequently, the model was simplified and workload was cut down. The preprocessed model was import to the ADAMS environment to build the virtual prototype model. A comparison between the simulation and the road test verified that the virtual prototype model met the requirements of virtual experiment. The extreme roll angle and maximum climbing slope were obtained by ADAMS simulation to avoid hazardous vehicle test on sloping area. In addition, the terrain trafficability of the corn harvester on the weak ground was analyzed with cone index.
