Vibration Suppression: Reduced-order Model/residual Mode Filter Control Using Smart Structures - Aerospace Conference, 1998 IEEE
For spacecraft with large flexible antennas, andor flexible support structures, suppressing vibrations caused by on-orbit operational disturbances (e.g., antenna slew maneuvers and thruster firings) is a challenging problem. In the past several years, advances in smart structure technologies have made their use in real-time dynamic control cif a structure possible. This paper discusses analytic...
متن کاملHybrid Passive/Active Impact Detection & Localization for Aerospace Structures
This paper presents finding from a recent set of formal performance assessments studies, quantifying the ability of a hybrid passive/active SHM system to detect impact damage. The SHM system itself is an integrated device including an array of PZT sensors with a central PZT actuator, analog-to-digital converter, memory and FPGA. In passive mode, the system uses the central PZT element for trigg...
متن کاملPerformance of Tuned Liquid Dampers with Different Tank Geometries for Vibration Control of Structures
TLD is a tank filled with water and serves as a dynamic vibration absorber for passive control of structures. This paper addresses the comparisons of TLD performances corresponding to different tank geometries including rectangular and conical shapes. Due to the importance of water and tank weight as a load on top of a building, volume is considered to be a constant parameter in this study. Fir...
متن کاملPassive vibration control: a structure-immittance approach.
Linear passive vibration absorbers, such as tuned mass dampers, often contain springs, dampers and masses, although recently there has been a growing trend to employ or supplement the mass elements with inerters. When considering possible configurations with these elements broadly, two approaches are normally used: one structure-based and one immittance-based. Both approaches have their advanta...
متن کاملVibration Control of Structures with Initially Accelerated Passive Tuned Mass Dampers under Near-Fault Earthquake Excitation
This article deals with the applicability of passive tuned mass damper (PTMD) for reducing the dynamic responses of structures under near-fault earthquake excitations. Three types of pulse-like time functions are employed to simulate the near-fault ground motion. The vibration control effectiveness of PTMDs is extensively investigated through the comparisons of response spectrum and response ti...
