STOCHASTIC LINEARIZATION OF SYSTEMS WITH HYSTERETIC CHARACTERISTICS
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2014, Vol 59, Issue 3
Abstract
In this paper is presented a linearization method for a stochastic differential system with hysteretic characteristics and random excitation. The Gaussian equivalent linearization technique is applied to a system with hysteretic characteristic modeled by a Bouc-Wen equation. In order to verify the efficiency of the linearization method, the standard deviations of the equivalent linear system response are compared with those of Bouc-Wen nonlinear system for two case studies: Gaussian white noise and seismic inputs.
