【摘要】 本文研究了联合收割机液压油管空间弯曲成形的设计问题。建立了液压油管空间弯曲成形的数学模型,编制了计算与绘图程序。设计者只要输入液压油管中心线空间弯曲成形的节点(端点)总数及各点的坐标值和弯曲半径值,计算机便可自动计算出液压油管空间弯曲成形所需的全部参数,并绘制出液压油管中心线空间弯曲成形图。更多还原

【Abstract】 In this paper, the space bending formation of hydraulic oil tube of combine harvester is studied, the mathematical model of it is established and the procedure for calculation and drawing is worked out, All the technical parameters required by the space bending formation of hydraulic oil tube can be automatically calculated by the computer and the drawing for centre line space bending formation of hydraulic oil tube is designed only when all number of nodal points (end points)of centre line space bending formation of hydraulic oil tube and each of co-ordinate value and bending radius are inputed by the designer.更多还原
