| Solving a stochastic problem for systems subjected to random series of pulses is, in the present case, aimed at determining of an approximate distribution of amplitudes of random pulses forcing vibrations of an oscillator with damping. The applied model of investigations indicated the source of difficulties connected with interpretation of the obtained results. Another issue discussed in the paper is how a change of the damping coefficient b of the system may result in a decrease of the difference between the actual distribution of random pulses and that determined from the waveform. |
