Abstract: For the aluminum honeycomb sandwich panel with SCSC edge supports, the dynamic response numerical calculations were conducted using the Ansys by considering the range and quantity of the filling particles in cell of honeycomb sandwich panel. The stress and strain of the honeycomb sandwich panel in different conditions were further compared. The result indicates that filling particles in the panel cell can well reduce the stress and strain and increase the energy absorption effect. When the range of filling particles is from 0.2 to 0.25 and the quantity of filling particles is 2, the stress and strain of honeycomb sandwich panel are minimal and the effect of the energy absorption is best. Too much filling particles do not have a better energy absorption effect but conversely can shock the honeycomb sandwich panel.

Key words: honeycomb sandwich panel, impact loading, particles, filling range, quantity of filling particles
