Popis:	A simple stochastic method for generating synthetic orbital accelerations is proposed in this paper. The procedure is used to develop a stochastic model for the STS-40 orbital excitation. The method uses a filtered white-noise model that takes into account time evolutions of the amplitude and the frequency content of the original accelerogram. The probabilistic response spectra are generated and comparisons with those of the actual STS-40 orbital data are made to verify the model. The results indicate that significant properties of the original record are retained in the generated synthetic accelerations. This method is also employed to generate a stochastic model for the space station vibration environment.
