一、概述 在纤维缠绕中要实现稳定缠绕,就必须保证缠绕纤维沿着曲面上两点之间的最短距离——“短程线”又名“测地线”进行铺线。曲面上测地线的方向方程和轨迹方程在微分几何中已经推导出来了,在工程中如何去设计缠绕机的运动以实现测地线缠绕,成为产品设计、设备设计和工艺人员所共同关心的问题。75年从西德引进的WE-250脉冲数宇控制液压伺服纤维缠绕机的所有资料是按芯模上的放线进行实测仿型描绘制作控制小车和伸臂运动的“控制凸轮”,没有谈到能否设计计算或如何
I. Overview In order to achieve stable winding in the fiber winding, it is necessary to ensure that the winding fiber is laid along the shortest distance between two points on the curved surface - “geodesic”, also known as “geodesic”. The geodesic geodesic direction equations and trajectory equations have been deduced in differential geometry. How to design the movement of the winding machine to achieve the geodesic winding in the project has become a common concern of product design, equipment design and process personnel problem. 75 years from West Germany introduced WE-250 pulse number of Yu-controlled hydraulic servo fiber winding machine all the information is based on the mandrel on the line of the actual profile modeling depicting the production of control car and boom movement “control cam”, did not mention Can design calculations or how?
