| Abstract: | A impact between freely moving object and primary oscillator follows the one-step memory Markov process after maklng an investigation into the single degree of freedom system to using impact damper under the action of random excitation is indicated. The transferab1e probability density function of the impact attenuation vibration system is deduced. |
