In order to satisfy both stability and uniform coverage of the fiber traj ectory,in contrast to the conven-tionally used geodesic winding,the equations of fiber patterns for non-geodesically filament-winding pressure vessels were proposed and the optimal design approaches for non-geodesic patterns and winding parameters were presented. The relative winding velocities of the mandrel and the feed eye for toroidal vessel were analyzed.The optimal pat-terns were adj usted according to the uniform coverage condition.Through the application of computer simulation techniques to the design and verification of toroidal vessel winding patterns,the CAD system was studied on the functions and implementation methods,the simulations of computer graphics and tests for non-geodesic filament-winding were realized.The results show that the designed non-geodesics satisfy the basic requirements for the wind-ing process,and through the optimal non-geodesics winding patterns,the non-geodesic angles are centralizing around 5 5°,which are the optimal winding angle for cylindrical pressure vessels,and consequently improve the structural bearing capability of pressure vessels.
