As a part of the ongoing sustainability strategy program within Velux, it has been decided that all the plastic components used for packaging of the products are replaced by other more sustainable counterparts. Within this context a numerical model was generated to simulate the side and 3D drop tests used for standardization of the packaging quality. In these tests, the product is dropped from a certain height to a sensor plate at the ground and is tilted in such a way that it either lands on its side or one of its corners. The sensor plate records the impact forces and helps evaluate the dissipation of these forces by the packaging material. However, considering a wide range of products within Velux many tests need to be conducted, thus a numerical model was also generated in order to speed up the process. The model evaluates the impact absorption capabilities of various honeycomb structured card boards in comparison to the existing EPS material both for the side drop and 3D drop tests. Simulations were conducted in Abaqus/CAE and the explicit solver was used for the solutions. The results of the simulations indicated very close correlation with the lab tests and help predict optimum honeycomb structure that is required for different products.
