Impact of configuration errors on the dynamic oscillation absorbers effectiveness of different masses on the seismic resistance of bridges
Tashkent Institute of Railway Engineers, Adilkhodjaev st., 1, 100067, Uzbekistan
Analyzes existing known solutions for dynamic damping oscillations of bridges in earthquakes. Substantiates the impact of errors settings the two-mass systems on the efficiency of dynamic dampers of different masses (small, large and commensurate). Based on the obtained of optimal parameters were built isolines depending reduce the displacement of the main mass of the setting on the stiffness and damping for different masses. The estimates obtained allow to simplify essentially the task of designing seismic devices for bridges.
