文摘
- •
Random vibration problems for Rayleigh vibroimpact system with a rigid barrier are considered.
- •
The random excitation is Parametric Poisson white noise.
- •
The averaged generalized Fokker-Planck-Kolmogorov equations for vibroimpact system with parametric Poisson white noise are derived.
- •
The approximate stationary responses are solved by perturbation method.
- •
Effects on the response for different damping coefficients, restitution coefficients and noise intensities are discussed.
