Structural Modification Focusing on Reactive Structural Intensity

Currently, Active Structural Intensity is mainly used for energy propagation evaluation in Intensity analysis. Therefore, this paper examines structural changes focusing on Reactive Structural Intensity, that expresses stationary component of energy transmission. We have derived the structural change sensitivity of Reactive Structural Intensity as well as Active Structural Intensity. Numerical simulation was performed with a spring mass damper system with four degrees of freedom. From the results of the sensitivity analysis, we achieved a reduction in intensity by adding mass.
