  • The influence of loading trajectory was discussed to solve the precisi on forming problem of double curve skin in stretch forming. The method of combin g finite element analysis and optimization algorithms was proposed to acquire th e reasonable loading trajectory. Characteristic and insufficiency of common load ing trajectories were analyzed which used in double curve skin forming. Optimiza tion mathematics model was set up in order to reduce springback and improve the fittability. Approximate model and variables range were set up with orthogonal d esign. The reasonable loading trajectory was found through the numerical simulat ion and sequential quadratic programming optimization algorithm under the restri ctive of maximal thickness strain. The optimization results show that the fittab ility, strain distributing and thickness uniformity were improved greatly.
