ON DYNAMICS STOCHASTIC EVALUATION OF EMBEDDED SYSTEMS PROTECTION AGAINST VIBRATION

This research provide a simple method intended for evaluation of dynamic performances of vibration protective devices used for embedded systems protection. The whole work was based on the fact that authors supposed and performed a large number of instrumental and virtual tests, for different kind of protective devices. This paper deal with a short and conclusive presentation of theoretical support for a stochastic approach of the vibration isolation dynamics. The main advantage of this new approach result from the characteristics of the most usual encounted dynamic perturbances - most of all are unpredictable, having an aleatory evolution in time, with a large and various spectral compositions. The stochastic approximation could offer a gainful solution of this problem, regarding both the input characteristics, and the output perceptions.
