(2017-12-04)Data are available for a previously tested annular seal with no swirl brakes (NSB). The NSB seal design was modified by adding slots at the inlet to produce a swirl brake (SB) seal. Tests were conducted to evaluate the ...
-
(2012-07-16)This research compares the leakage and rotordynamic characteristics of a slanted-tooth labyrinth seal to a conventional straight-tooth labyrinth. Detailed results comparing the rotordynamic coefficients and leakage parameters ...
-
(2015-08-11)The present work investigates the damping potential of carbon nanotube (CNT) reinforced polymer matrix composites through integrated experiments and continuum modeling techniques. Both “passive" and “active” damping are ...
-
(2016-05-03)The recent seismic scale that the world has been experiencing, with earthquakes of uncommon intensity has triggered the alarms of the world scientific community due to the devastating aftermaths in terms of infrastructure ...
-
(2012-10-19)The study of mechanical energy and electrical energy dissipation in cementitious materials can lead to development of high damping concrete for structural applications, and new non-destructive testing techniques for use ...
-
(2015-10-01)With the rapid growth of the transportation industry (automotive and aerospace), the demands for the control of noise and enhancing the stability of structures, through the development of high damping materials are continually ...
-
(Texas A&M University, 2005-02-17)In this study the energy dissipation performance of machine augmented composite (MAC) materials is investigated. MAC materials are formed by inserting simple machines into a matrix material. In this work the machines ...

Measurements of the Static and Dynamic Load Performance of a Water Lubricated Hybrid Thrust Bearing (2019-02-07)After a successful static load testing campaign in 2015, the thrust bearing test rig has been reconfigured for dynamic load tests to determine force coefficients (stiffness, damping, and added mass). Continuous lubrication ...

(2012-12-10)Gas bearings in oil-free micro-turbomachinery for process gas applications and for power generation (< 400 kW) must offer adequate load capacity and thermal stability, reliable rotordynamic performance at high speeds and ...
-
(2013-04-22)Previous work on modal analysis of mooring lines has been performed from different theoretical formulations. Most studies have focused on mooring lines of a single homogeneous material, and the effect of added mass and ...
-
(2014-07-24)Moored buoy systems are often deployed by oceanographers to gather scientific information on local and global changes in the water column, weather patterns and climate change. The data they gather is first transmitted to ...
-
(2010-01-16)In the last 35 years, several researchers have proposed, developed and tested different friction devices for seismic control of structures. Their research has demonstrated that such devices are simple, economical, practical, ...
