An in-plane flexible ring model for the analysis of the free and forced response of a rolling tyre
INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2023 The increased demand for vibroacoustic comfort as well as regulations on noise and vibration levels have made the NVH (Noise, Vibration, Harshness) performances of a vehicle to become one of the fundamental design criteria. Therefore, predictive models for the analysis of noise and vibration transmission mechanisms represent interesting tools to ...

A Computer Program for Simulating Cambial Activity and Ring Growth
, 1975 This paper describes an interactive computer program which simulates daily cell growth and differentiation in a single radial file of tree cells. The growth processes are controlled by 22 model parameters, half of which are constants, the remainder time ...

The Decomposition of Tree-Ring Series for Environmental Studies
, 1987 Signal extraction in tree-ring research is considered as a general time series decomposition problem. A linear aggregate model for a hypothetical ring-width series is proposed, which allows the problem to be reduced to the estimation and extraction of ...

A survey of low-velocity collisional features in Saturn's F ring [PDF]
, 2014 Small (~50km scale), irregular features seen in Cassini images to be emanating from Saturn's F ring have been termed mini-jets by Attree et al. (2012). One particular mini-jet was tracked over half an orbital period, revealing its evolution with time and

A modified complex modal testing technique for a rotating tire with a flexible ring model [PDF]
Mechanical Systems and Signal Processing, 2015 Abstract Natural frequencies, mode shapes and modal damping values are the most important parameters to describe the noise and vibration behavior of a mechanical system. For rotating machinery, however, the directivity of the propagation wave of each mode should also be taken into account.
