The software for evaluating vibration parameters from transport and stationary sources

Original language description

The software provides the possibility of hygienic evaluation of vibrations from a 3-axis measuring point according to Government Regulation No. 241/2018 Coll., standard ČSN 730040 Loads of buildings by technical seismicity. The calculation conditions are based on standards ČSN ISO 4866, ČSN ISO 2631-1 to ČSN ISO 2631-5. The software also includes other functions for selecting and processing measured data.

Eval. of vibrations from transp.

Technical parameters

It is assumed that the data to be evaluated comes from one measuring point and is distributed over three axes X, Y, Z. Time data for processing can be loaded in several formats depending on the device used, the first option is the "csv" format, then from the text format from the Pulse system (Bruel&Kjaer) and the third "uff". The output of the first method is the effective acceleration value, or the effective acceleration value level and the third-octave spectrum of the vibration acceleration. The calculated characteristics are frequency-weighted by the Wm function. In the case of the second method, it is the effective oscillation speed and the third-octave spectrum of the oscillation speed. Other software functionality includes selection (trimming) of the data set of measured data according to the selected time interval, data filtering with a software filter (Butterworth) in the form of upper, lower and bandpass filters, calculation of basic statistical parameters, amplitude spectrum using FFT and Welch's method and calculation of Short-term Fourier Transform. In addition to calculation and presentation, the software provides the ability to save the calculated parameters in the "csv" format and images with graphs in the "png" format.

Economical parameters

This is a simple and inexpensive evaluation software focused on evaluating vibrations from various types of sources and various devices according to Government Regulation No. 241/2018 Coll. and the ČSN 730040 standard Loads on buildings by technical seismicity. The software represents a very inexpensive solution that can be used for routine vibration evaluation within the framework of custom work, as well as when processing scientific and research papers and within the framework of teaching. The author also expects to use it in professional subject exercises. The software will speed up and make the evaluation of performed tests and measurements more accurate. Currently, such oriented software does not exist on the software and teaching aid market, so its price is difficult to estimate.
