(2011-10-21)The present work investigates the phenomena of whip and whirl for a rigid rotor contacting at two bearing locations. The idea originated from an anemometer consisting of a rotor with an elastically supported stator undergoing ...
-
(2009-05-15)Cotesia are parasitoid wasps (Hymenoptera: Braconidae) that are used for biological control of pest moths (Lepidoptera: Noctuidae, Pyralidae) that damage agricultural crops. This dissertation investigated courtship acoustics ...
-
(2015-05-13)In this dissertation, the influence of using induction motor in machinery train on rotordynamics is discussed. Two areas are considered – the use of variable frequency drives (VFDs), which control and drive the induction ...
-
(2017-01-24)This thesis starts from the construction of a mathematical model of the multi-segment mooring line, based on the work-energy variational method. The equations of motion in both Cartesian and Lagrange local coordinate systems ...
-
(2014-04-28)Artificial hydrophobic and superhydrophobic surfaces have been studied in the last ten years in an effort to understand the effects of structured micro- and nano- scale features on droplet motion and self-cleaning mechanisms. ...
-
(2019-03-26)Machinery trains with motor drives are widely used in industry. Motor related forces may become one of the sources of machinery vibrations. Motor eccentricity is one of the common phenomena that cause forces exerted on ...

(Texas A&M University, 2004-09-30)Internal friction has been known to be a cause of whirl instability in built-up rotors since the early 1900's. This internal damping tends to make the rotor whirl at shaft speeds greater than a critical speed, the whirl ...

(2018-11-30)Two animal models, growing pigs (n = 26) and yearling horses (n = 20), were used to test the hypothesis that whole body vibration (WBV) would improve bone density and composition. Digital radiographs with an aluminum step ...
-
(Texas A&M University, 2004-09-30)This thesis deals with a systematic procedure for the derivation of exact expression for the frequency equation of composite beams undergoing forced vibration with damping. The governing differential equations of motion ...
-
(Texas A&M University, 2004-09-30)Torsional vibration is an oscillatory angular twisting motion in the rotating members of a system. It can be deemed quite dangerous in that it cannot be detected as easily as other forms of vibration, and hence, subsequent ...
