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.
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.
