Experimental study on the electromechanical hysteresis property of macro fiber composite actuator
The hysteresis characteristic in macro fibre composite (MFC) actuator is intimately related to their application in vibration control system. In this paper, the electromechanical hysteresis property of MFC actuator is studied. First, experimental study on the electromechanical behaviours under different voltages and frequencies is carried out, and the hysteretic property of MFC actuator is investigated. A digital signal processing (DSP) system is used to control input voltage and a digital image correlation (DIC) system as noncontact setup is used to obtain the output strain of the MFC actuator in the experiment. The experimental results indicate that the relationship of the voltage and strain displays hysteresis with nonlocal memory. Second, the Preisach model is used to describe hysteresis characteristic of the MFC actuator. In order to improve the accuracy of the model, the modifications are made, in which the experimental data under the quasi-static frequency range and the congruency property are used to establish the modified Preisach model. Finally, the hysteresis characteristics of the MFC actuator predicted from the proposed model are compared with those obtained from the classical Preisach model. The results indicate that the proposed model gives better accuracy than the classical Preisach model, and it is suggested that the present study on the hysteresis model of the MFC actuator can be used in the active vibration control.
期刊介绍:
The International Journal of Acoustics and Vibration (IJAV) is the refereed open-access journal of the International Institute of Acoustics and Vibration (IIAV). The IIAV is a non-profit international scientific society founded in 1995. The primary objective of the Institute is to advance the science of acoustics and vibration by creating an international organization that is responsive to the needs of scientists and engineers concerned with acoustics and vibration problems all around the world.
Manuscripts of articles, technical notes and letters-to-the-editor should be submitted to the Editor-in-Chief via the on-line submission system. Authors wishing to submit an article need to log in on the IJAV website first. Users logged into the website are able to submit new articles, track the status of their articles already submitted, upload revised articles, responses and/or rebuttals to reviewers, figures, biographies, photographs, copyright transfer agreements, and send comments to the editor. Each time the status of an article submitted changes, the author will also be notified automatically by email.
IIAV members (in good standing for at least six months) can publish in IJAV free of charge and their papers will be displayed on-line immediately after they have been edited and laid-out.
Non-IIAV members will be required to pay a mandatory Article Processing Charge (APC) of $200 USD if the manuscript is accepted for publication after review. The APC fee allows IIAV to make your research freely available to all readers using the Open Access model.
In addition, Non-IIAV members who pay an extra voluntary publication fee (EVPF) of $500 USD will be granted expedited publication in the IJAV Journal and their papers can be displayed on the Internet after acceptance. If the $200 USD (APC) publication fee is not honored, papers will not be published. Authors who do not pay the voluntary fixed fee of $500 USD will have their papers published but there may be a considerable delay.
The English text of the papers must be of high quality. If the text submitted is of low quality the manuscript will be more than likely rejected. For authors whose first language is not English, we recommend having their manuscripts reviewed and edited prior to submission by a native English speaker with scientific expertise. There are many commercial editing services which can provide this service at a cost to the authors.
