Evaluation of transmissibility for a class of nonlinear passive vibration isolators

Z. K. PENG, Z. Q. LANG, G. MENG

Frontiers of Mechanical Engineering 2012, Volume 7, Issue 4, Pages 401-409 doi: 10.1007/s11465-012-0349-9

Abstract:

In this study, the concept of Output Frequency Response Functions (OFRFs) is applied to representthe transmissibility of nonlinear isolators in frequency domain.relationship between the transmissibility and the nonlinear characteristic parameters is derived for a wide classisolators can significantly suppress both the force and displacement transmissibility over the resonant frequency

Supervised topic models with weighted words: multi-label document classification None

Yue-peng ZOU, Ji-hong OUYANG, Xi-ming LI

Frontiers of Information Technology & Electronic Engineering 2018, Volume 19, Issue 4, Pages 513-523 doi: 10.1631/FITEE.1601668

Abstract: However, these models neglect the class frequency information of words (i.e., the number of classes whereTo address this, we propose a method, namely the class frequency weight (CF-weight), to weight wordsby considering the class frequency knowledge.This CF-weight is based on the intuition that a word with higher (lower) class frequency will be less

A frequency error estimation for isogeometric analysis of Kirchhoff–Love cylindrical shells

Frontiers of Structural and Civil Engineering doi: 10.1007/s11709-023-0006-x

Abstract: A frequency error estimation is presented for the isogeometric free vibration analysis of Kirchhoff–LoveBy analyzing the discrete isogeometric equations with the aid of harmonic wave assumption, the frequencyIn particular, the governing relationship of the continuum frequency for Kirchhoff–Love cylindrical shellsis naturally embedded into the frequency error measures without the need of explicit frequency expressionsNumerical results not only thoroughly verify the theoretical convergence rates of frequency solutions
