RISIdentification of Linearized Dynamic Characteristics of Rolling Element Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study presents a new method for estimating linearized coefficients of rolling element bearings. The rotor-bearing systems considered here are composed of a flexible shaft, which may be ...
Collocated Sensor/Actuator Positioning and Feedback Design in the Control of Flexible Structure System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a new control design method for the control of flexible systems that not only guarantees closed-loop asymptotic stability but also effectively suppresses vibration. This method ...
An Investigation of the Characteristics of Electromagnetic Bearings Using the Finite Element Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The load capacity of EMBs with a restricted air gap is usually small in comparison with that of traditional ball bearings. One possible way to overcome this limitation is to increase the ...
Investigation on the Steady-State Responses of Asymmetric Rotors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is to generalize the previous work by utilizing finite element formulation to accommodate the effects of both deviatoric inertia and stiffness due to asymmetry of flexible shaft and ...
The Analysis of Linear Rotor-Bearing Systems: A General Transfer Matrix Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A general transfer matrix method (GTMM) is developed in the present work for analyzing the steady-state responses of rotor-bearing systems with an unbalancing shaft. Specifically, we derived the ...
A Modified Transfer Matrix Method for Asymmetric Rotor-Bearing Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A modified transfer matrix method (MTMM) is developed to analyze rotor-bearing systems with an asymmetric shaft and asymmetric disks. The rotating shaft is modeled by a Rayleigh-Euler beam ...
Modeling and Diagnosis of Motion Error of Multi-Axis Machines Using a Ball Bar Test
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The contouring accuracy of a multi-axis machine has a critical effect on the quality of many advanced technology products. One of the best approaches to assessing the contouring performance of ...
Modeling and Analysis of the Intermediate Shaft Between Two Universal Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Unlike a single universal joint, in which the output shaft rotates with a fluctuating speed depending on the misalignment angle, a double universal joint is used to connect two offset shafts. ...
A Modified Transfer Matrix Method for Linear Rotor-Bearing Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The steady-state responses of linear flexible rotor-bearing systems are analyzed by the modified transfer matrix method. The transfer matrix has the advantage of solving the problems in frequency ...
Transient Analysis of an Asymmetric Rotor-Bearing System During Acceleration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with the transient vibration of asymmetric rotor systems during acceleration passing through several critical speeds at which synchronous or super-harmonic resonance occurs. The ...
