| Résumé : |
Improving the mechanical properties of hollow bodies using structural elements is not yet state-of-the-art in the blow molding industry. At the institute for plastics processing (IKV) at the RWTH Aachen University, an approach was developed for the computer-aided design of blow molded articles with stiffening structures. |

- FIGURES : 1. Blow molding line and mold for the production of test specimens - 2. Wall thickness distribution of a bottle with beads and a bottle without beads in the same process point - 3. Wall thickness distribution along the beads - 4. Input data of the process simulation in B-SIM - 5. Comparison of the simulated and measured wall thickness distribution of the bottles with and without corrugation structures - 6. Comparison of topload simulation and experimental investigations with and without corrugation structures - 7. Comparison of measured topload and topload simulation with adjusted wall thickness distribution according to the measurements - 8. Deterministic optimization : radius, number and distortion are normalized by the maximum values - 9. Comparison of the bottle without corrugation structures and the deterministically optimized bottle - 10K Stochastic optimization |
