Abstract
The paper presents a method for analyzing and understanding the dynamics of prototype designs of hydraulic damper under non-stationary load conditions. In the method proposed in this paper, a high-frequency first-principle model of a damper is linearized around a series of operating points which are obtained from a preceding numerical simulation of the model. As a result of multiple repetitions of an elementary linearization, a series of linearized models and their respective eigenvalues are collected over a certain period of operation time, corresponding to the duration of a non-stationary excitation signal.
