摘要
针对自动铺丝路径规划芯模面测地等距网计算的核心问题,即简便、高精度的测地线计算方法存在的缺陷,给出了一种改进的在CAD曲面上计算测地线的方法,给出了理论推导、算法的实现步骤以及流程图,并以实例验证了该算法的有效性。对新算法与已有算法在计算精度方面所做的分析比较证明该算法操作简单,具有较高的计算精度,适合路径规划所涉及的大规模测地线计算的精度要求。
In robotic fiber placement,the key is to compute geodesic offset net. This includes calculating geodesics simply and high- precisely. Aiming at the drawbacks of existing methods,it presents an improved method of computing geodesics on CAD surface. Besides it also gives the theoretical deduction,implementation steps,flowchart of the new algorithm and some examples. Comparing this method with the existing ones,it shows that the method is easy to operate and has higher precision,is suitable for large- scale computation of geodesics in robotic fiber placement.
