DETERMINING STRUCTURAL PERFORMANCE

Dynamics of high-rise axisymmetric structures

The article discusses the natural and forced oscillations of a "high-rise structure - dynamic vibration damper" system, focusing on its dynamic interactions. A mathematical model of this system has been developed, along with a calculation methodology, a numerical implementation algorithm, and a corresponding computer p...

Study on the Influence of Structural Parameters on the Performance of an Internal Feedback Hydrostatic Bearing

Hydrostatic spindles are key components in high-precision grinding machines. In this paper, an internal feedback radial–thrust combined hydrostatic bearing is proposed to improve the load-carrying performance of conventional hydrostatic spindles. The throttling structure is integrated into the bearing inner surface, an...

Comparative Analysis of Advanced Control Strategies for Vibration Control of Flexible Satellite Structures

Flexible satellite structures with lightweight solar panels are naturally prone to structural vibrations caused by attitude maneuvers, continuous environmental disturbances and deformation during deployment. These vibrations can lead to a decrease in pointing accuracy, a degradation in payload performance, and an adver...
