METHOD OF SIMULATING NON-STATIONARY STOCHASTIC PROCESSES Russian patent published in 2012 - IPC G01M7/00 

FIELD: physics.

SUBSTANCE: method of simulating non-stationary stochastic processes comprises procedures for setting and generating in a control loop signals of stationary and non-stationary components of the realised process, as well as summation of said components while maintaining a feedback mode in the control loop. The method is characterised by that, the non-stationary component is generated by strobing and subsequent filtration of signal time intervals set by the source of the stationary component. A signal from a harmonic signal generator can be selected for strobing and filtration, and the non-stationary component can be generated by narrow-band filtering. The stationary component can be generated using a random signal with zero intervals which are filled with non-stationary components of the realised process.

EFFECT: invention enables to simulate non-stationary stochastic processes together with a stationary process, which increases quality of laboratory testing of articles for dynamic effect.
