本文介绍了悬挂犁机组性能设计的一种解析方法及其相应的 GTL-P 程序。该法利用解析几何原理按一定顺序求已知直线的交点,依次解出悬挂犁机组纵垂面和水平面诸未知力,以数组形式存于机内,相当于机内作图。最后输出诸参数并绘制二面的力多边形。使用本程序可在不足三分钟内完成一次悬挂犁机组性能设计,更换参数可迅速找到合理的设计方案。 This paper presents an analytical method for the performance design of a plow unit and its corresponding GTL-P program. This method uses the principle of analytic geometry to find the intersection of known straight lines according to a certain sequence, and then unknowns the vertical vertical plane and horizontal plane of the hanging plow unit in turn, and stores them in the form of an array, which is equivalent to the mapping in the machine. Finally output the parameters and draw the two-sided force polygons. Use this program can be completed within less than three minutes suspension plow performance design, replacement parameters can quickly find a reasonable design.
