Abstract:

This paper analyzes the causes of prepreg distortion and discusses its influence for the requirement of trajectory placement ability. A new algorithm of geodesic generation based on meshed surfaces is proposed according to the definition of geodesic, which possesses features of efficiency and highaccuracy, etc. Both the manufacturability of the prepreg and its distribution of strength in a product are considered in the algorithm of path planning, providing it with the ability of adapting to surfaces. The algorithm first figures out the maximum geodesic curvature allowed for the central path, and applies it to the design of trajectory. The trajectory obtained both has good ability of placement and can satisfy the demands of strength distribution in a product. Finally, the path planning aiming at one type of S-inlet with database of SQL Server and VC++ is carried out. The disperse trajectory points are then fitted to be a curve in CATIA to verify the validity and effectiveness of the algorithm of geodesic generation and trajectory placement generation.
