Experimental Investigation Into the Effect of Fluid Viscosity on Instability of an Over-hung Flexible Rotor Partially Filled With Fluid
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of fluid viscosity on the developing process of the instability in an over-hung flexible rotor partially filled with fluid, the dynamical behavior of the rotor system while the ...
Modeling and Simulation of Mold and Die Grinding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Complex molds and dies often need grinding to achieve the required surface finishes and tolerances. Due to complex part geometry and multiple-axis motion, the wheel–workpiece engagement conditions ...
A Modeling Study of the Episodic Cross-Frontal Water Transport over the Inner Shelf of the South Atlantic Bight
Publisher: American Meteorological Society
Abstract: Physical processes that control the episodic cross-frontal transport over the inner shelf of the South Atlantic Bight were examined using a 3D primitive turbulent closure equation model. The model results showed that ...
Specific Material Removal Rate Calculation in Five-Axis Grinding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Specific material removal rate (MRR) q′ was calculated for five-axis grinding in a virtual machining simulation environment (VMSE). The axis-symmetric tool rotational profile was arc-length parameterized. The twisted grazing ...
FrameGraph: A Scalable Performance Evaluation Method for Frame Structure Designs Using Graph Neural Network
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multilayer perceptron (MLP) and convolutional neural network (CNN) encounter a critical scalability issue when applied to the performance evaluation task for frame structure designs. Specifically, a model of MLP or CNN is ...
A Numerical Study of Stratified Tidal Rectification over Finite-Amplitude Banks. Part I: Symmetric Banks
Publisher: American Meteorological Society
Abstract: Tidal rectification over a two-dimensional finite-amplitude symmetrical bank is studied using the Blumberg and Mellor primitive equation coastal ocean circulation model (ECOM-si). In the homogeneous case, the nonlinear ...
Characteristics of Micro Gas Journal Bearings Based on Effective Viscosity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: According to the first order slip velocity boundary, a modified Reynolds equation for micro gas journal bearings is presented with consideration of effective viscosity under a rarefied flow ...
A Uniform Control Method for Imbalance Compensation and Automation Balancing in Active Magnetic Bearing-Rotor Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The undesired synchronous vibration due to rotor mass imbalance is a main disturbance source in all rotating machinery including active magnetic bearing (AMB)-rotor systems. In the AMB-rotor ...
A Numerical Study of Stratified Tidal Rectification over Finite-Amplitude Banks. Part II: Georges Bank
Publisher: American Meteorological Society
Abstract: Tidal rectification over an idealized two-dimensional cross section of Georges Bank, which is a large, shallow, elongated submarine bank in the Gulf of Maine, is studied using a primitive equation coastal ocean circulation ...
