Abstract

a study to predict numerically the structure-borne powers in a simple T-beam structure was conducted the goal of the study was to help align the procedures and measurement quantities used by the analytic, numerical, and experimental structure-borne noise communities. The T-beam structure is similar to the T-shaped beam problem identified by the longitudinal and flexural vibrational waves was predicted for low to mid-range frequencies. A finite element (NASTRAN) model was used to predict the vibration field of the truss, and the post-processor McPOW (Mechanical POWer) was used to calculate the structure-borne powers. Power component percentage plots show the ratios of axial and flexural power traveling into and out of the T-joint.
