Shock-Cushioning and Energy Absorption Performance Research of Aluminum Foam-Polyurethane Composite

Abstract:

The paper researched stress and strain of aluminum foam, polyurethane and aluminum foam-polyurethane composite via Ansys software, researched energy absorption capacity of the three material via energy absorption curve method, and researched energy absorption capacity of the aluminum foam-polyurethane composite under different shock and different thickness. The research results are obvious: under the same material parameter and 7800gn shock conditions the energy absorption of the aluminum foam-polyurethane composite is better than the monomer of the aluminum foam and the polyurethane. Under the same shock conditions, the thicker the composite is, the more energy it absorbs. Aluminum foam-polyurethane composite can plays cushioning and energy absorption roles when the acceleration speed reaches 7800gn
