摘要：

The stochastic linearization technique, widely used for the analysis of nonlinear dynamic systems subjected to random excitations. is revisited. It is shown that the standard procedure universally adopted for determining the so-called effective stiffness of the equivalent linear system is erroneous in all previous publications. Two error-free stochastic linearization techniques are elucidated, namely those based on (1) the force linearization and (2) energy linearization. (C) 1997 Elsevier Science Ltd.
