Identification of Asymmetric Bouc–Wen Hysteresis Under Intense Noise by Only Measuring Acceleration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Parameter identification of hysteretic models is significant for predicting structural dynamic response in vibration isolation structures. However, quasi-static testing and displacement measurement methods are not convenient ...
Transient Response Control of Two Mass System via Polynomial Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper discusses the application of polynomial method in the transient response control of a benchmark twomass system. It is shown that transient responses can be directly addressed by specifying the socalled characteristic ...
Nonlinear Response Identification of an Asymmetric Bistable Harvester Excited at Different Bias Angles by Multiscale Entropy and Recurrence Plot
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to their high sensitivity to excitations with low intensity, bistable energy harvesting systems have received significant attention. In practical applications, it is difficult to achieve a bistable energy harvester ...
Nonlinear Dynamic Characteristics of Variable Inclination Magnetically Coupled Piezoelectric Energy Harvesters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the nonlinear dynamic characteristics of a magnetically coupled piezoelectric energy harvester under low frequency excitation where the angle of the external magnetic field is adjustable. The nonlinear ...
Nonlinear Dynamic Analysis of a Cracked Rotor Bearing System With Fractional Order Damping
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fatigue cracking of the rotor shaft is an important fault observed in the rotating machinery of key industries, which can lead to catastrophic failure. Nonlinear dynamics of a cracked rotor system with fractional order ...
A Pseudo-Static Model for Dynamic Analysis on Frequency Domain of Distributed Compliant Mechanisms
