Title :Mn基合金の内部摩擦を考慮した振動シミュレータの検討
Authors :鞆田 顕章
Issue Date :Dec-2018
Abstract :Accurate estimation method of the vibration response for a mechanical system using Molecular dynamics method (MD) is considered. This study focuses on the MD modeling for estimating energy dissipation in Manganese-based alloys under vibration. The phenomenon of energy dissipation in metal is caused by internal friction. In manganese-based alloys such as M2052 alloy, internal friction occurs by the formation of twins in the material under external force. In this paper, the result of experimental modal analysis for obtaining values of natural frequency and damping ratio of M2052 plate is reported. In addition, the development of a large-scale MD simulator for estimating of displacement and velocity of atoms in pure Manganese single crystals under a very low temperature is investigated.
