Trajectory planning algorithm based on pyramidal inclined winding

Abstract

Inclined winding is a new fiber belt winding technology proposed by technicians for the production and manufacture of high-speed aircraft with conical shells. In order to meet the trajectory path planning of inclined winding technology, a spiral algorithm for inclined fold winding is proposed considering the designability of process parameters such as inclined fold angle and stepping distance. For the cone or pyramid with the central axis, the spiral slice algorithm is used to obtain the path points of an oblique winding according to the actual core model, including the establishment of a reference line, reference track point, inclined winding angle, oblique winding center track point and path point information acquisition. Finally, using Visual Studio 2019 as the development platform and VB.NET language, the pathplanning software of the algorithm is programmed. The trajectory simulation and experimental verification are carried out on the path of inclined winding prepreg fiber belt for cone and pyramid. The verification of the effect diagram proves the feasibility of the algorithm.
