Abstract:
This paper is devoted to the computation of second-order moment functions of the solution of large- scale systems of linear random ODEs which arise in the modeling of randomly excited linear vibration systems. Model reduction techniques are applied to find approximations of the desired moment functions of the large-scale system by computing them for a suitable low-dimensional system. Numerical results concerning transverse vibrations of thin beams are presented.
