In order to satisfy the requirement of stable and uniform fiber trajectory, the fiber linear equation of non-geostrophic fiber wound pressure vessel is proposed, which is different from the traditional geostrophic wind mode. The optimal design method of the parameters was used to analyze the relative winding speed ratio of the toroidal core and the nozzle, and the optimal linearity was adjusted with the uniform covering conditions. The computer simulation technology is applied to the design and verification of the winding container of the toroidal vessel. The functions and the realization methods of the components of the CAD system are studied. The computer graphics simulation and inspection of the non-geodesic winding are carried out. The results show that the designed geodesic can meet the basic requirements of the winding technology. Using the optimized geodetic winding mode, the winding angle of the geodetic line can be concentrated in the optimal winding angle of the cylindrical pressure vessel by 55 ° Nearby, effectively improve the structural bearing capacity of the pressure vessel.
