Journal ArticleDOI
Analytical modeling and validation of multi-mode piezoelectric energy harvester
TL;DR: It is shown that the multi-mode PEH has potential to generate sufficient power output from broadband vibration sources to sustain low-power electronic devices.
Journal ArticleDOI
Estimation of modal parameters using the sparse component analysis based underdetermined blind source separation
Kaiping Yu,Kai Yang,Yunhe Bai +2 more
TL;DR: The underdetermined blind source separation method based on sparse component analysis in the time–frequency domain is introduced to estimate the modal parameters in this study and the extracted results evidently show the thermal effect on themodal parameters.
Journal ArticleDOI
Vibration and acoustic responses of composite and sandwich panels under thermal environment
Xiangyang Li,Kaiping Yu +1 more
TL;DR: In this paper, the authors focused on the vibration and acoustic responses of the sandwich panels constituted of orthotropic materials applied a concentrated harmonic force in a high temperature environment and derived the critical temperature to prevent the thermal load excess.
Journal ArticleDOI
Accurate modeling and analysis of a typical nonlinear vibration isolator with quasi-zero stiffness
Chaoran Liu,Kaiping Yu +1 more
TL;DR: In this article, a more accurate dynamic model is established with consideration of these practical factors, and the dynamic behavior and dynamic characteristics of a typical quasi-zero stiffness (QZS) isolator are analyzed based upon the accurate model.
Journal ArticleDOI
A high-static–low-dynamic-stiffness vibration isolator with the auxiliary system
Chaoran Liu,Kaiping Yu +1 more
TL;DR: In this article, an auxiliary system is added to the HSLDS isolator to overcome the disadvantages, with the static displacement of the isolation object remaining unchanged, which can lower the peak transmissibility and eliminate the jump phenomenon, resulting in a wide isolation region.
