Self-Excitation in Guided Circular Saws
(The American Society of Mechanical Engineers (ASME), 1988)The paper presents the results of an experimental and analytical study into the vibrational characteristics of guided rotating saw blades that are not perfectly flat. Experimental results are ... -
Experimental Study on the Static and Dynamic Characteristics of Screw Grooved Seals
(The American Society of Mechanical Engineers (ASME), 1988)Screw grooved annular seals are used in many heavy duty pumps such as boiler feed pumps. These annular seals have a significant effect on rotordynamic characteristics of the pumps. Studies on ... -
Advanced Techniques for Measuring Structural Mobilities
(The American Society of Mechanical Engineers (ASME), 1988)A unified formulation of the equations for estimating structural frequency response functions is presented. The more popular approaches are shown to be special cases of a general equation which ... -
Instability and Unbalance Response of Dissymmetric Rotor-Bearing Systems
(The American Society of Mechanical Engineers (ASME), 1988)The study deals with the instability and unbalance response of dissymmetric rotors, when periodic differential equations are impossible to avoid. The method which yields motion instability is ... -
Excitation Force Identification of Rotating Machines Using Operational Rotor/Stator Amplitude Data and Analytical Synthesized Transfer Functions
(The American Society of Mechanical Engineers (ASME), 1988)Hydraulic excitation forces of rotating machinery are normally determined by direct measurement techniques like strain gages, load cells, etc. This paper presents an indirect method, in which ... -
Hybrid Finite Element—Boundary Element Simulation of Rotating Machinery Supported on Flexible Foundation and Soil
(The American Society of Mechanical Engineers (ASME), 1988)Relative and absolute shaft vibration data have revealed that the commonly made assumption of rigidly supported bearings may be grossly inaccurate, especially for fans, generator sets, and natural ... -
Electromagnetic Control of Oil-Film Supported Rotors Using Sparse Measurements
(The American Society of Mechanical Engineers (ASME), 1988)An electromagnetic controller is applied to a flexible rotor supported by two oil-film bearings. The synchronous vibration is controlled by using a combined estimation and optimization algorithm. ... -
