Research and Verification on Damping Performance of Magnesium Alloy

Abstract

The paper analyzes the length variety of the crystal gain and sub-crystal gain of magnesium alloy materials during the strain amplitude augmentation in the linearity stage of the material deformation, and then based on G-L model derives the mathematical model of the damping variety durign the strain amplitude augmentation in the linearity strain stage of the magnesium alloys. Consequently, magnesium alloy damping mechanism is studied theoretically. It is proved that the magnesium alloy material has the advantages of high damping capacities. In addition, a comparison test in terms of damping performance is made between magnesium alloy and other alloys, which further confirms the high damping of magnesium alloy and the rightness of the theoretical deduced conclusion.
