RISDevelopment of a Multiphase Flamelet Generated Manifold for Spray Combustion Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, a model flame of quasi-one-dimensional (1D) counterflow spray flame has been developed. The two-dimensional (2D) multiphase convection-diffusion-reaction equations have been simplified to one dimension using ...
Influences of Tooth Crack on Dynamic Characteristics of a Multi-Stage Gear Transmission System Considering the Flash Temperature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The crack failure is prone to happen for the gear teeth under alternating loads. The crack reduces the time-varying meshing stiffness, thus causing changes in the system vibration responses. Moreover, the tooth friction ...
Robust Adaptive Control of Antagonistic Tendon-Driven Joint in the Presence of Parameter Uncertainties and External Disturbances
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The design of nonlinear tracking controller for antagonistic tendon-driven joint has garnered considerable attention, whereas many existing control methodologies are impractical in the real-time applications due to complexity ...
Sea Level Variations in the Tropical Pacific Ocean and the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: Satellite observations of sea level and surface wind from the tropical Pacific Ocean, and their relationship to the Madden?Julian oscillation (MJO), are analyzed using a combination of statistical techniques and a simple, ...
Nonlinear Control of a Quadrotor With Deviated Center of Gravity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a new adaptive tracking controller is developed for a quadrotor unmanned aerial vehicle (UAV) via immersion and invariance (I&I) approach. The controller is able to compensate parametric uncertainties ...
Characterization of Spatial Parasitic Motions of Compliant Mechanisms Induced by Manufacturing Errors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a theoretical model for characterizing manufacturing error induced spatial parasitic motions (MESPM) of compliant mechanisms (CM), and investigates the inherent statistic features of MESPM using Monte ...
Different Scale Experiments of High Velocity Penetration With Concrete Targets
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, two different scale projectile high velocity penetration experiments with concrete targets that had an average compressive strength of 35 MPa were conducted in order to find the velocity limits and nose ...
Research on the Application of Fen for Environmentally Assisted Fatigue Evaluation of the Austenitic SS Pipe Under Combined Transient Loads
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Accumulative test data indicate that the effects of the light water reactor (LWR) environment could cause the fatigue resistance of primary pressure boundary components materials to be significantly reduced. Environmentally ...
Smart Rotor With Trailing Edge Flap Considering Bend–Twist Coupling and Aerodynamic Damping: Modeling and Control
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Aerodynamic damping and bend–twist coupling significantly affect the dynamic response of wind turbines. In this paper, unsteady aerodynamics, aerodynamic damping, and bend–twist coupling (twist-towards-feather) are combined ...
