Magnetic Bearing With Rotating Force Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A common attractive type active Magnetic Bearing (AMB) was designed and tested with three parallel feedback control loops. The feedback of the measured AMB journal displacement provides the ...
A Modified Conical Beam Element Based on Finite Element Analysis: Experimental Correlations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A portion of the results from a previous investigation into the structural behavior of hollow conical sections has been used to develop a method of correcting the conical beam element used ...
Operation of an Electromagnetic Eddy-Current Damper with a Supercritical Shaft
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A basic problem inherent with the operation of supercritical shafting is the application of appropriate external damping, which is generally necessary to suppress nonsynchronous instabilities and ...
Analytical and Experimental Evaluation of Instability in Rotordynamic System With Electromagnetic Eddy-Current Damper
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: There have been a number of papers published that concern the design and operation of electromagnetic, eddy-current dampers for controlling lateral vibration of rotating machinery. Many of these ...
Application of the Principle of Reciprocity to Flexible Rotor Balancing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The least desirable feature of most flexible rotor balancing procedures is the considerable number of trial mass runs required. This is of particular importance in the balancing of machines ...
The Effects of Strain and Temperature on the Dynamic Properties of Elastomers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the results of a program of analysis and tests to determine the dynamic, properties of elastomers as a function of strain and ambient temperature. Measurements were also ...
Torsional Stability Analysis of a Gas-Turbine Powered Helicopter Drive System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The torsional stability of a closed-loop dynamic system is evaluated. The system is a typical transport helicopter speed governor, gas-turbine engine and drive train. This is compared with the ...
Demonstration of a Unified Approach to the Balancing of Flexible Rotors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A flexible rotor balancing procedure, which incorporates the advantages and eliminates the disadvantages of the modal and influence coefficient procedures, has been developed and implemented. This ...
The Dynamic Characteristics of O-Rings
Publisher: The American Society of Mechanical Engineers (ASME)
Extension of the Transfer Matrix Method for Rotordynamic Analysis to Include a Direct Representation of Conical Sections and Trunnions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The transfer matrix method for rotordynamic analysis (alternately known as the HMP or LMP method) has enjoyed wide popularity due to its flexibility and ease of application. A number of computer ...
