Study of the response of a single-dof dynamic system under stationary non-Gaussian random loads aimed at fatigue life assessment.

Fatigue assessment of components subjected to random loads is a challenging task both due to the variability in amplitude and frequency of the loads and for the computational times required to perform classical time domain fatigue analysis. The frequency domain approach to fatigue life assessment offers a solution by utilizing the power spectral density of the random load, requiring minimal computational effort. However, frequency domain methods are limited to stationary Gaussian signals, while real-world loads often exhibit non-Gaussian characteristics.

Definition of simulated driving tests for the evaluation of drivers' reactions and responses.

Objective: This article aims at identifying the most significant measures in 2 perception-response (PR) tests performed at a driving simulator: a braking test and a lateral skid test, which were developed in this work.

Methods: Forty-eight subjects (26 females and 22 males) with a mean age of 24.9 ± 3.
