Study on the mechanism of unidirectional loading rubber bulging of bionic egg-shaped shell

Aiming at the problems of complex processing technology, uneven deformation, and poor forming accuracy multi-curvature positive Gaussian slewing egg-shaped shells, it is proposed to use unidirectional loading rubber flexible medium bulging technology improve tube deformation distribution enhance plastic bionic shells. By analyzing structure manufacturing method this paper explores optimization in non-homogeneous The simulation analysis experimental verification methods are used study different technological parameters shells under master mechanism shell structural components loading. shows that optimizing mode can effectively uniformity strain thickness during thus improving thin-walled parts. Furthermore, after good agreement with experiment.
