An experiment on the vibrational characteristics of a hybrid gas bearing-rotor system in a 45 kW high-speed permanent magnet machine test rig is conducted... D Han,J Yang,C Chen,... 被引量: 1发表: 2014年 Crack Fault Diagnosis and Location Method for a Dual-Disk Hollow Shaft Rotor Syste...
The major study was done on shaft by using different materials with different shaft profile of Solid and Hollow with two and Three Cracks. A natural frequency was analyzed and critical speed was predicted by using Campbell diagram and analysis was also performed for validation....
Microcomputed tomography (µCT) of femurs revealed that the long bones of 5-week-oldSOXCOsxCremale and female mice had a smaller cortical area (78% and 83%, respectively) than those of sex-matched controls and that this difference was largely maintained in adulthood (7–52 weeks; averages...
n = 3, at least 200 cells were manually counted for each experiment. Error bars are SEM Full size image Our results show the requirement of MT polyglutamylation for efficient PPLL elongation in D723H cells. The striking localization of PolyE marks to the bundling MTs at the leading ...

In general, the Os% in the g-C3N4 and GO implanted defects displayed a highly significant difference (P < 0.05) compared with the control defect throughout the experiment (Fig. 6A). At 4 weeks, the Os% in g-C3N4 implanted defects (54.30 ± 5.71%) was significantly higher th...
In this work, a procedure to obtain an accurate value of the critical speed of a cracked shaft is presented. The method is based on the transversal displacements of the cracked section when the shaft is rotating at submultiples of the critical speed. The
