【摘要】 针对直接利用高密度压捆机对牧草高密度压缩过程进行研究时 ,传统的试验研究和理论分析方法存在的问题 ,对牧草的高密度压捆过程进行了计算机分析与仿真研究。引入了虚拟样机技术 ,使用 ADAMS软件对牧草的高密度压捆过程进行分析 ,建立压缩过程中牧草的 ADAMS模型 ,并对 ADAMS的建模方式、模型结构进行了验证。通过分析获得模拟弹簧的刚性系数 k随时间的变化规律 ,进而对牧草压缩工况进行优化分析。更多还原

【Abstract】 Computer analysis and simulation for study of high density hay bales compressing process were carried out. The virtual prototype technology and software package , ADAMS, were adopted in the analysis of bale compressing process. A mathematica l model of hay compressing process for ADAMS was established. The variations of the stiffness coefficient of the virtual spring along time were obtained and an optimization analysis for hay compressing conditions was made.更多还原
