RISDynamic Characteristics Analysis of a Seal-Rotor System With Rub-Impact Fault
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Labyrinth seals are widely used to prevent fluid leakage in high-low pressure areas of the rotating machinery. However, the rub-impact fault easily occurs in labyrinth seals. Considering the influence of gyroscopic effect, ...
Research on the Buckling Load of Clamped Spherical Caps Under External Pressure: Analyzed by the Fourier Series Model With Initial Geometric Imperfections
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The knockdown factor (KDF), which characterizes the difference between the actual buckling pressure and the classical theoretical pressure of clamped spherical caps under external pressure, is highly discrete. The mechanism ...
Use of Pipeline Wave Propagation Model for Measuring Unsteady Flow Rate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel method for estimation of unsteady flow rate using pressure at two or three points along a pipeline is described in this paper. The pressure data are processed using a wave propagation model to determine the unsteady ...
Interdecadal Variation of Precipitation over the Hengduan Mountains during Rainy Seasons
Publisher: American Meteorological Society
Abstract: AbstractThe present study investigates the interdecadal variation of precipitation over the Hengduan Mountains (HM) during rainy seasons from various reanalysis and observational datasets. Based on a moving t test and ...
Contact Characteristics Analysis of Deep Groove Ball Bearings Under Combined Angular Misalignments and External Loads
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to the uncontrollable factors in the installation process, the angular misalignments of the inner and outer races may exist in deep groove ball bearings. In order to analyze the performances of bearings with misalignments, ...
Origins of Biases in CMIP5 Models Simulating Northwest Pacific Summertime Atmospheric Circulation Anomalies during the Decaying Phase of ENSO
Publisher: American Meteorological Society
Abstract: AbstractThe present study documents the biases of summertime northwest Pacific (NWP) atmospheric circulation anomalies during the decaying phase of ENSO and investigates their plausible reasons in 32 models from phase 5 ...
