Abstract:To solve the problem of excessive residual strain of fiber in conical shell laying process, a trajectory planning method with constant geodesic curvature is proposed. Analysis shows that the geometric curvature of the trajectory determines the residual strain of the fiber. The expression for the constant curvature curve is then derived by calculating the geometrical curvature of the arbitrary curve on the cone, and the constant geodesic curvature curve is proved to be a circular arc on the conical surface. The trajectory laying process is analyzed by calculating the residual strain of the constant geodesic curvature trajectory and its angle with the conical busbar. The results show that the constant geodesic curvature trajectory is better designability and laying processability than the fixed angle trajectory and the geodesic trajectory. © 2017, Press of Chinese Journal of Aeronautics.
