Description: The design of the structural connections is important from the standpoint of reducing      system vibration amplitudes or enhancing joint damping capacity. A state-of-the-art      review was performed and a generic experimental model was developed and      constructed. The test model consists of two concentric circular cylindrical shells and four      vanes connected by groups of bolts. First, a finite element model was developed and      analyzed, using the MSC/NASTRAN computer program. The first analysis was a modal      survey of the model to investigate dynamic characteristics of the whole system. Secondly      a frequency response analysis gave the input/output relationship between an input point      (excitation) and an output point (response) in the frequency domain, which depends on      the damping characteristics of the structure.
