摘要
对现有联合收割机、脱粒机的典型机构一平台逐稿器机构图形形成的独立闭链有关方程写成矩阵形式,采用机构最优化设计中的下降法对机构进行运动分析,把机构各构件位移、(角)速度、(角)加速度变化规律,通过图表,形象、清楚地表现出来.采用闭链活动度准则计算机构自由度。
A terrased rack′s mechanism is the typical one of recent combine harvesters and thrashing machines. The independent and closed equations, which are formed by the graph of that mechanism, are written out as matrix form. The descent method is used to analyse the movement of mechanism. The change law of every mechanism component′s displacement,(angle) velocity, and (angle) acceleration is il- lustrated imaginably and clearly by disgram. The free degree of mechanism is caculated by the criterion of closed chain activity degree.
