Vibration diagnostics is of particular importance in rail transport safety systems because the signals received from vibration sensors installed on rolling stock, bridges, tunnels, and other infrastructure objects have great diagnostic information potential. Despite this, in practice, there are cases when the adequacy of the results of the vibration control and diagnostics task is not ensured. The...
Transport infrastructure objects are exposed to a large number of loads, which cause the formation of displacements, bends, wear, cracks, breakdowns, corrosion, and other defects. It is shown that at the moment of initiation of malfunctions in objects, the noise of the noisy signals coming from the corresponding sensor takes critical values that correlate with useful signals. Therefore, algorithms...
It is shown that correlation matrices and normalized correlation matrices are applied in solving of static and dynamic identification problems for diagnostics and prediction of technical condition and seismic stability of high-rise buildings and building structures. Specific characteristics and properties of those matrices are determined.
Existing methods and corresponding equipment for determining seismic stability of high-rise buildings and construction structures have been analyzed. Robust noise technology has been developed, which allows performing concurrent monitoring of change in seismic stability of all control objects after each weak earthquake. A distributed robust system for monitoring of seismic stability of socially significant...
Problems of monitoring of seismic stability and technical condition of high-rise buildings, building structures and strategic objects in seismically active regions at early stages of fault origin with application of known methods of calculation of dispersion, correlation, spectral, static and dynamic characteristics have been analyzed. Technologies and algorithms have been offered for solving of this...
