Frequency Domain Dynamic Analysis of Large Space Structures with Added Elastomeric Dampers
Modern computer-based computational techniques such as the finite element method enable the structural dynamicist to make precise calculations of the mass and stiffness properties of complex large space structures (LSS). To obtain dissipation analysis up to the same level of sophisitcation as mass and stiffness analysis in damped structures, an equally accurate methodology is required. This paper presents one such methodology for LSS with added elastomeric dampers. Elastomeric dampers have been used in the different parts of LSS to absorb part of the vibrational energy, and to help reduce the damage caused by the dynamic forces. The purpose of this paper is to present the specturally formulated finite element analyses for damped LSS. Using the fractional derivative model, the non-linear damping characteristics of elastomeric dampers have been modelled.
