Based on the theory of space analytic geometry and kinematics,fiber鄄touched point爷s locus equation
of flat winding about FRP spherical pressure vessel is established. The functions of fiber鄄touched point爷s space loca鄄
tion,and velocity and acceleration of equal polar hole spherical pressure vessel爷s flat winding at any time are de鄄
duced. Velocity in various directions and cosine value of angular separation of the fiber鄄touched point were solved by
the analysis of doff point爷s winding principle. Finally,winding locus is simulated with various initial angles by software
of Matlab,the effectiveness of the proposed approach is validated by the comparison results of numerical simulation and
actual fiber winding style.
