RISActive Vibration Control of Beams by Combining Precompressed Layer Damping and ACLD Treatment: Performance Comparison of Various Robust Control Techniques
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is a well known fact that system parameters of the flexible structures keep on changing due to several reasons. Ordinary controllers lose their effectiveness in changed situations and do ...
Modeling, Nonlinear Dynamics, and Bifurcation Analysis of the Rotor–Seal System Using a Subharmonic Sampling Strategy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rotors are used to transfer power from one component to the other component in various rotor dynamics applications like steam turbines, aerospace systems, and power generators. In certain applications, the seal is an ...
Pole Placement Techniques for Active Vibration Control of Smart Structures: A Feasibility Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is well known that there is degradation in the performance of a fixed parameter controller when the system parameters are subjected to a change. Conventional controllers can become even ...
Online Chatter Detection for Milling Operations Using LSTM Neural Networks Assisted by Motor Current Signals of Ball Screw Drives
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For certain combinations of cutter spinning speeds and cutting depths in milling operations, self-excited vibrations or chatter of the milling tool are generated. The chatter deteriorates the surface finish of the workpiece ...
Active Vibration Control of Beams By Combining Precompressed Layer Damping and ACLD Treatment: Theory and Experimental Implementation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: By attaching initially stressed poly vinyl chloride (PVC) layers on the flexible structures, necessary passive damping can be provided. Using passive constrained layers on these PVC layers, the ...
Performance Analysis of Finite Element and Energy Based Analytical Methods for Modeling of PCLD Treated Beams
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For active/passive vibration control applications, low order models of flexible structures are always preferable. Mathematical models of passive constrained layer damping (PCLD)/active constrained ...
Community Sensor Network for Monitoring Road Roughness Using Smartphones
Publisher: American Society of Civil Engineers
Abstract: Maintenance of ever-expanding road networks all over the world is a critical task and regular monitoring of the road surface is imperative for successful maintenance. Existing monitoring techniques use dedicated vehicles ...
Simultaneous Fault Detection and Multivariable Adaptive Hybrid Control for Unbalanced Vibrations of Cracked Flexible Rotor Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For the reduction of unbalanced vibrations in a multi-input and multi-output flexible rotor system with electromagnetic actuators (EAs), conventional adaptive feedforward controllers (AFFCs) are very sensitive for changes ...
Performance of Thermally Sprayed Nickel and Tungsten-Based Coatings in Slurry Erosion Conditions: A Review
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The energy needs of a country cannot be fulfilled by a single source of energy, so renewable energy sources like solar, wind, and hydro energy are widely used throughout the world. In countries where sufficient hydro energy ...
Optimized Near Minimum Time Control of Flexible Structures Using Variable Gain (LQG) Control Strategies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A neural network based time optimal control of flexible structures is presented. The implementation is done on a flexible inverted L structure with surface-bonded piezoceramic sensors/actuators. ...
