Random Vibrations: Assessment of the State of the Art
23.02.1999Random vibration is the phenomenon wherein random excitation applied to a mechanical system induces random response. We summarize the state of the art in random vibration analysis and testing, commenting on history, linear and nonlinear analysis, the analysis of large-scale systems, and probabilistic structural testing.

Mechanical and Structural Vibration: Theory and Applications
01.07.2001The first chapter gives an introduction into the derivation of the equations of motion for discrete systems. The equations for planar systems are derived by Newton-Euler's equations. As a second possibility, the Power Balance Method is presented for time-invariant systems. In addition, Lagrange's Equations are shown in the appendix.
