Response of the impact damper to stationary random excitation

The response of an impact damper system to an excitation with approximately white-power spectral density and Gaussian probability distribution is determined, using two independent methods: digital computer and electronic-analog techniques. Results are given for mean-squared level, power spectral density, probability density, probability distribution, and amplitude probability density of the response. The impact damper is found to be a practical and efficient device for reducing the response amplitude of systems subjected to random excitation.
