As an embodiment of the present invention, in S2, the three-dimensional engine is a Unity engine.
As a specific embodiment of the present invention, the simulation control of S3 includes the following specific processes:
s31, before starting the simulation process, firstly creating two empty position variables v1 and v2, setting a certain position point on the left side of the winding drum as a winding starting point A, setting a certain position point on the right side of the winding drum as a winding ending point B, and respectively storing the position information of the point A and the point B as variables vA and vB;

The dynamic generation method of the wire in winding comprises the following steps: designating a radius alpha with the point a and the point B on the reel represented by the position information stored in v1 and v2 as a start point and an end point, calculating a winding angle alpha, and creating a series of position variables from the start point and the end point, the radius and the winding angle alpha; drawing a hexagon at the starting point and the ending point respectively, designating material, dynamically drawing points, lines and surfaces according to the winding speed1 and the traversing speed2 to form a line model, connecting the two ends of the line model with the vertexes corresponding to the hexagons of the starting point and the ending point, and adding the generated line model into a collision body.
The ratio of the traverse speed2 of the yarn guide to the rotational speed1 of the drum determines the winding angle α at which the wire is wound on the drum, tan α = speed2/speed 1.
