| Popis: | Based on experience from the testing of the mining stacker in the copper mine in Bor, a practical procedure of frequency simulation of the enforced vibration of the structure was demonstrated. Modelling of the excitation was performed by the harmonic function of the eccentric mass of the belt conveyor drive. The paper shows how the drive frequency excitation affects the amplitude of vibration of the supporting structure. From this, the idea is presented - an algorithm for software that would allow for keeping the dynamic properties of the members of the structure within controlled range. An experiment for accelerating the structure and its FFT analysis in the frequency domain was performed. Dynamic modelling of the structure allows obtaining the objectivised concept of the measurement system for monitoring based on the given level of dynamic sensitivity of the parts of the structure. |
