Frequency domain

In this paper, the static and dynamic behaviour of sandwich beams with porous core are numerically analyzed and validated by experimental tests. The beam consists of a thick porous core with a uniform porosity distribution over its domain and two outer face layers.

The C-EPS steering system's performance is affected by a range of technical parameters, including steering column inertia, steering column stiffness, column damping, rack stiffness, rack damping, and steering column pinion radius. The simulation results in both the frequency domain and the time domain indicate the influence of structural parameters on the system characteristics.

This paper presents a comparative study of two different forward methods such as the space domain method and the frequency domain method. The performance of each method was evaluated on two synthetic models. Finally, the more effective method was applied to calculate Bouguer gravity anomaly in the East Vietnam Sea and adjacent areas using the latest available dataset from the TOPEX mission.

This thesis aimed to apply the SEM for dynamic analysis of cracked beam subjected moving harmonic force in the frequency domain. Namely, the frequency response of a cracked beam subjected to moving harmonic force is obtained explicitly and examined in dependence upon the load and crack parameters. This task is acknowledged herein spectral analysis of cracked beam subjected to moving load.
