Response of a Hard Spring Oscillator to narrow band random excitation

Abstract

This Thesis Project has two main objectives: First, to develop a frequency response equation for narrow band random excitation of a nonlinear Hard Spring Oscillator from a statistical point of view and then make a comparison to the already known sinusoidal case. Secondly, the frequency response equation develop is analysed by varying the excitation bandwidth and the excitation force. Numerical results are obtained and frequency response curves are plotted and analysed.
