Optimization of non-linear mass damper parameters for transient response
We optimize the parameters of multiple non-linear mass dampers based on numerical simulation of transient wave propagation through a linear mass-spring carrier structure. Topology optimization is used to obtain optimized distributions of damper mass ratio, natural frequency, damping ratio and nonlinear stiffness coefficient.
Large improvements in performance is obtained with optimized parameters and it is shown that nonlinearmass dampers can bemore effective for wave attenuation than linear mass dampers.
