摘　　要：为实现复杂曲面相贯线的切割和焊接,需要对切削轨迹进行控制,通过齐次坐标变换建立圆锥管-圆管相贯的复杂曲面相贯模型,推导空间相贯线及其平面展开曲线的表达式,通过Matlab软件对正交、斜交、正交偏置及斜交偏置4种模型的相贯线及其平面展开曲线进行编程仿真,验证曲线模型的正确性,使用Origin软件对相贯线平面曲线进行分段拟合,并对其进行误差分析,为复杂管件曲面的相贯线研究提供实验数据。To realize the cutting and welding of complex surface curve intersecting line,cutting track is controlled,the complex curved surface intersecting model of conical pipe circular pipe is established through secondary coordinate transformation,and the expression of spatial intersecting line and its plane expansion curve is deduced.With Matlab software,the intersection line and its plane expansion curve of the four models of the orthogonal,oblique,orthogonal offset and oblique offset are programmed and simulated to verify the correctness of the curve model.Origin software is used to fit the plane curve of the intersection line and its error are analized,which provides experimental data for the reserch on the intersection line of complex pipe fitting surface.
