Abstract:

Impact experiment equipment was used to study the dynamic mechanical properties and characterization method of a new kind of damping aluminum alloy under impact load. Results show that the material’s mechanical and damping properties can be characterized scientifically and appropriately by the impact work and energy parameters obtained by the impact experiments. The shock resistance ability of the new kind damping aluminum alloy is higher than that of the general cast aluminum alloy by 86%, while the damping property is higher by 37%.
