Experimental and Numerical Study of Grout Effectiveness and Force-Transfer Mechanism in Socket Connections
Publisher: ASCE
Abstract: This study aims to investigate the effectiveness of grout and the mechanism of force transfer in socket connections. In doing so, it proposes a new transfer mode called integral transfer mode (ITM), as opposed to the ...
Aircraft Closed-Loop Dynamic System Identification in the Entire Flight Envelope Range Based on Deep Learning
Publisher: American Society of Civil Engineers
Abstract: To solve the aircraft dynamics modeling problem in the entire envelope range, this work proposes a closed-loop system identification method based on deep learning. A closed-loop flight test was designed, under the framework ...
Overland-Flow Resistance Characteristics of Nonsubmerged Vegetation
Publisher: American Society of Civil Engineers
Abstract: In order to discover the resistance characteristics of overland flow with vegetation cover, indoor drainage experiments with six slopes, seven flow discharges, and five degrees of vegetation cover are systematically ...
A New Low-Frequency Resonance Sensor for Low Speed Roller Bearing Monitoring
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The resonance demodulation technique has been widely used to detect rolling bearing faults based on the signal acquired by piezoelectric accelerometers. However, this method is ineffective in ...
Recognition of Freeform Surface Machining Features
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a method of machining feature recognition from a freeform surface based on the relationship between unique machining patches and critical points on a component’s surface. ...
Investigation of Aerator Flow Pressure Fluctuation Using Detached Eddy Simulation with VOF Method
Publisher: ASCE
Abstract: The detached eddy simulation model and volume of fluid (VOF) method were combined to simulate the pressure fluctuations in the downstream region of an aerator in a spillway tunnel, which often lead to hydraulic structure ...
