Abstract
A circular pipe filament winding process simulation method includes: according to the geometric parameter of the circular pipe and the current pseudo dome parameter, constructing the stepped shaft circular pipe model; according to the winding parameter, calculating the initial center rotation angle for filament winding; according to the initial center rotation angle and the given deviation rotation angle, calculating the theoretical center rotation angle; according to the theoretical center rotation angle, determining the theoretical slip coefficient within the given slip coefficient range; determining whether the slip coefficient of the end point of the current stepped shaft circular pipe model is less than the current theoretical slip coefficient; if so, performing the simulation of the circular pipe filament winding process, and obtaining the trajectory according to the current theoretical slip coefficient; and if not, modifying the current pseudo dome parameter, and returning steps of constructing the stepped shaft circular pipe model.
