RISFeedback Control of Self Sustained Nonlinear Combustion Oscillations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Detrimental combustion instability is unwanted in gas turbines, aeroengines, rocket motors, and many other combustion systems. In this work, we design and implement a sliding mode controller (SMC) to mitigate selfsustained ...
Construction Behavior of Double Down-side Drifts in a Weak Tunnel with Shallow Cover
Publisher: American Society of Civil Engineers
Abstract: Confronted with accidents in a shallow-buried weak tunnel using the bench excavation method, such as great subsidence and cracks in the ground surface as well as those in the preliminary support, a double downside drifts ...
Coulomb Friction Crawling Model Yields Linear Force–Velocity Profile
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Conventional wisdom would have it that moving mechanical systems that dissipate energy by Coulomb friction have no relationship between force and average speed. One could argue that the work done by friction is constant ...

Study of the Effect of Air Injection on the Surge and Flow Characteristic of Compressor and the Pumping Loss in a Heavy-Duty Turbocharged Natural Gas Spark Ignition Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, bench tests of a heavy-duty turbocharged natural gas spark ignition engine were conducted with intake air injection at full load and different engine speeds. The flow characteristic of the compressor was ...
Effect of Electromagnetic Force on Dynamic Mechanical Properties of the Magnetorheological Elastomer Under Compression Mode
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Under the compression mode, the direction of force on the magnetorheological elastomer (MRE) is parallel to the direction of electromagnetic force, so the effect of electromagnetic force on its dynamic mechanical properties ...
