RISInstability in Nonlinear Oscillation of Dielectric Elastomers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A membrane of a dielectric elastomer oscillates when subject to AC voltage. Its oscillation is nonlinear due to large deformation and nonlinear electromechanical coupling. Dynamic instability in dielectric elastomers—the ...
Are the Transient and Equilibrium Climate Change Patterns Similar in Response to Increased CO2?
Publisher: American Meteorological Society
Abstract: After a CO2 increase, whether the early transient and final equilibrium climate change patterns are similar has major implications. Here, we analyze long-term simulations from multiple climate models under increased CO2, ...
Recent Winter Precipitation Changes over Eastern China in Different Warming Periods and the Associated East Asian Jets and Oceanic Conditions
Publisher: American Meteorological Society
Abstract: lobal-mean surface temperature has experienced fast warming during 1985-1998 but stabilized during 1999-2013, especially in boreal winter. Climate changes over East Asia between the two warming periods and the associated ...
Soft Freestanding Planar Artificial Muscle Based on Dielectric Elastomer Actuator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dielectric elastomer actuators (DEAs) exhibit interesting muscle-like attributes including large voltage-induced deformation and high energy density, thus can function as artificial muscles for soft robots/devices. This ...
Research on Hybrid Energy Storage Configuration in Grid Wind Power Scheduling Tracking Under Statistics and Frequency Decomposition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The low accuracy of wind power scheduling influences the grid dispatch adversely, increasing the demand for spinning to reserve capacity and obstructing the grid frequency regulation. Considering the throughput characteristics ...
Bio-Inspired Soft Swim Bladders of Large Volume Change Using Dual Dielectric Elastomer Membranes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The buoyancy control mechanism is critical for undersea robots to achieve effective vertical motion. However, current buoyancy control mechanisms are associated with problems such as complex design, bulky structure, noisy ...
Influence of 650 °C Thermal Aging on Microstructure and Creep–Fatigue Behaviors of P92 Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, P92 steel was subjected to thermal aging treatment at 650 °C for 800 h, and then basic mechanical and creep–fatigue test was performed. The creep–fatigue cycle response trend is consistent before and after ...
The Different Configurations of the East Asian Polar Front Jet and Subtropical Jet and the Associated Rainfall Anomalies over Eastern China in Summer
Publisher: American Meteorological Society
Abstract: o investigate the concurrent impacts of the East Asian polar front jet (EAPJ) and subtropical jet (EASJ) on the summer rainfall over eastern China, positive (strengthened EAPJ with weakened EASJ) and negative (weakened ...
Dielectric Elastomer Fluid Pump of High Pressure and Large Volume Via Synergistic Snap-Through
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Harnessing reversible snap-through of a dielectric elastomer (DE), which is a mechanism for large deformation provided by an electromechanical instability, for large-volume pumping has proven to be feasible. However, the ...
Contributions of Different Combinations of the IPO and AMO to the Concurrent Variations of Summer East Asian Jets
Publisher: American Meteorological Society
Abstract: Huang et al. recently reported that opposite phases of the interdecadal Pacific oscillation (IPO) and the Atlantic multidecadal oscillation (AMO) can affect the shift of the East Asian polar front jet (EAPJ) and the East ...
