RISEffects of Compound Groove Texture on Noise of Journal Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The noise of a journal bearing with the compound groove textures is studied based on computation fluid dynamic (CFD) theory and broadband noise source theory. In doing so, the acoustic power levels of the noise for the ...
Evaluation of Ride Comfort and Driving Safety for Moving Vehicles on Slender Coastal Bridges
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Evaluating driving safety of moving vehicles on slender coastal bridges as well as bridge safety is important to provide supporting data to make decisions on continuing or closing the operations of bridges under extreme ...
Coupled Dynamic Analysis of the Vehicle-Bridge-Wind-Wave System
Publisher: American Society of Civil Engineers
Abstract: Slender bridges, often built in harsh coastal environments, may experience dynamic loadings from strong winds and high waves. Busy traffic is expected during normal operating conditions and during evacuation events before ...
Vibration Frequencies and Modes of a Z Shaped Beam With Variable Folding Angles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we investigate the vibration characteristics of a Zshaped beam with variable folding angles which is used to model a folding wing of a morphing aircraft under the condition of a fixed structure. The governing ...
Parametric Identification of Nonlinear Vibration Systems Via Polynomial Chirplet Transform
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The response of a nonlinear oscillator is characterized by its instantaneous amplitude (IA) and instantaneous frequency (IF) features, which can be significantly affected by the physical properties of the system. Accordingly, ...
Influence of Solid Rubber Coating on the Response of Floating Structure to Underwater Shock Wave
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The influence of solid rubber coating on the transient response of floating structure to underwater shock wave is experimentally and numerically studied. A stiffened metal box coated with solid rubber tiles on the outer ...
Friction Induced, Self Excited Vibration of a Pantograph Catenary System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A dynamic model of a pantographcatenary system is established. In the model, motion of the pantograph is coupled with that of the catenary by friction. Stability of the pantographcatenary system is studied using the finite ...
Mechanism of Optimal Targeted Energy Transfer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel nonlinear vibration reduction mechanism based on targeted energy transfer (TET) is proposed. Targeted energy transfer is a physical phenomenon that describes a one-way irreversible energy flow from a linear oscillator ...
Experimental and Numerical Study on the Reduction of Residual Stress in the Fillet Weld by Overlay Welding and Cutting Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fillet weld joint is widely used in engineering structures, but a lot of failures have been generated in the fillet joint affected greatly by weld residual stress, and it is very important to decrease the residual stress. ...
