RISBlade Vibration Stress Determination Method Based on Blade Tip Timing Simulator and Finite Element Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Blade tip timing (BTT) measurement technology is more widely used to determine the vibrational stress of rotating blades and play an important role for blade service life prediction. The dynamic blade displacements can be ...
Analysis Method of Nonsynchronous Vibration and Influence of Tip Clearance Flow Instabilities on Nonsynchronous Vibration in an Axial Transonic Compressor Rotor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The relationship between the tip clearance flow (TCF) and the blade vibration in the lock-in region was numerically investigated on a transonic rotor. Both the bending (1B) and torsional (8th) modes were analyzed under 0 ...
An Experimental Study on Air-Water Two-Phase Flow Patterns in Pebble Beds
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental study was conducted on the air-water two-phase flow patterns in the bed of rectangular cross sections containing spheres of regular distribution. Three kinds of glass spheres ...
Fatigue Life Prediction of Vortex Reducer Based on Stress Gradient
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of stress gradient and size effect on fatigue life are investigated based on the distribution of stress at the notch root of notched specimens of GH4169 alloy. The relationship between the life of notched ...
An Integrated Dual Ultrasonic Selective Powder Dispensing Platform for Three-Dimensional Printing of Multiple Material Metal/Glass Objects in Selective Laser Melting
