SIMULATION OF EXPERIMENTAL DAMPING DETERMINATION OF ELASTIC SYSTEMS
Vibrations analysis is important part of construction design and possible failure detection. Vibration highly depends on damping characteristics. Damping characteristics must be considered or determined experimentally, which is commonly done by analysis of vibration records. Determination of damping is important due that internal damping of elastic systems sometimes could be controlled to reduce amplitude of vibrations and increase a life of construction. In this paper, simulation of experimental damping determination of elastic systems is presented. Vibrations are simulated by numerical solution of mathematical model of damped vibrations of two d.o.f. system. Waveform obtained by simulation is imported in software for experimental data analysis and analysed as a real waveform. Damping analysis is performed in time domain and tested for different initial condition.
