RISReal-Time Estimation of Human Arm Dynamic Parameters Based on Optical
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A flexible optical intensity sensor is designed in this study to address the poor adaptability of fixed-value parameters in exoskeleton research, which makes it difficult to handle system changes and uncertainties. The ...
Additive Manufacturing of Horizontal and 3D Functionally Graded 316L/Cu10Sn Components via Multiple Material Selective Laser Melting
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Production of functionally graded materials (FGMs, i.e., a gradual transition from one material to another) and components is challenging using conventional manufacturing techniques. Additive manufacturing (AM) provides a ...
Onset of Flow Separation Phenomenon in a Low-Specific Speed Centrifugal Pump Impeller
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The efficiency of centrifugal pumps drops sharply when the flowrate is reduced below a threshold value. This is due to a profound change in the flow structure, characterized by a large of portion flow separation near the ...
Dynamic Stall Inception and Evolution Process Measured by High-Frequency Particle Image Velocimetry System in Low Specific Speed Impeller
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Stall in centrifugal pumps is a complicated flow phenomenon, which is detrimental to the pumps' safety and stable operation. Using a high-frequency particle image velocimetry (PIV) system (f = 10k Hz) and a bench-scale ...
