Passive vibration control of space structure by receptance theory

The vibration of three_dimensional frame structures was studied as receptance motion. A receptance model was constructed for passive vibration reduction. First, the universal receptance computational method suitable to any combination of boundary conditions was given, and then the way of passive damping_damping elements was analyzed, and an iterative approach to select optimal damping positions, whose dissipated power is larger than the others, was proposed based on the results of receptance analysis. The results show that, the receptance model is very suitable for local modification and analysis of structures.
