Summary

In the paper is presented the application of Green's multi-dimensional function to determine the probabilistic characteristics of the solutions of stochastic linear equations with time-variable coefficients, with random initial conditions and random excitations.

The method is applied to calculate the variances of solutions for the vibrations of a vehicle model (or suspension) accelerated over a random profile.

Anwendung der Greenschen Funktion zur Untersuchung von stochastischen Schwingungen dynamischer Systeme

Übersicht

Die Greensche Funktion wird angewendet zur Ermittlung des Lösungsverhaltens stochastischer, linearer Differentialgleichungen mit zeitabhängigen Koeffizienten, mit Zufalls-Anfangsbedingungen und mit Zufalls-Erregung. Die Methode wird in einem Anwendungsbeispiel (Schwingungen eines beschleunigten Fahrzeugmodells) demonstriert.
