Research on the Vibration Simulation of Particle Damping Sheet Based on Power Flow

Computer simulation was applied to study the power flow of particle damping sheet in order to achieve the vibration characteristics. Firstly,the vibration equation of the particle damping sheet was established by discrete modeling.And the equation was solved to get the power flow expression by Laplace transform.Secondly,the power flow was simulated by computer programming in Matlab so that the curves could be got. At last,the simulation results were analyzed to discover the vibration characteristics of the particle damping sheet.
