Modelling and control of an impacting flexible circular ring
2001 European Control Conference (ECC), 2001In this paper, the problem of damping the impact induced vibrations of a circular ring is studied. Finite dimensional models of the structure are derived, based on the use of the eigenfunctions of the vibrating structure. The impacts are modelled by using the Valentine variables method in order to take into account the presence of the inequality ...

Modeling of a Rolling Flexible Circular Ring
Journal of Applied Mechanics, 2015The motion equations of a rolling flexible circular ring are derived using a Lagrangian formulation. The in-plane flexural and out-of-plane twist-bending free vibrations are modeled using the Rayleigh–Ritz method. The motion equations of a flexible circular ring translating and rotating in space are first developed and then constrained to roll on a ...

Modeling of Spur and Helical Gear Planetary Drives With Flexible Ring-Gears and Planet Carriers
Volume 5b: Power Transmission and Gearing Conference, 2005Abstract A model is presented which enables the simulation of the three-dimensional static and dynamic behavior of planetary/epicyclic spur and helical gears with deformable parts. The contributions of the deflections of the ring gear and the carrier are introduced via substructures derived from 3D finite element models. Based on a modal

In-Plane Flexible Ring Tire Model Parameter Identification: Optimization Algorithms
SAE International Journal of Vehicle Dynamics, Stability, and NVH, 2018<div>Parameter identification is an important part of tire model development. The prediction performance of a tire model highly depends on the identified parameter values of the tire model. Different optimization algorithms may yield different tire parameters with different computational accuracy.

The flexibility of the cyclotrisiloxane ring as discussed in a strongly anharmonic vibrational model
Journal of Molecular Structure, 1977Abstract The puckering vibration of the cyclotrisiloxane ring is investigated in a strongly anharmonic potential, containing quadratic and quartic parts and an infinite barrier at selected maximum allowed amplitudes. From the two different assignments given recently for the A 2 '' puckering mode, 46 cm −1 and 391 cm −1 , respectively, the results ...

Optimization Algorithm Comparison for In-Plane Flexible Ring Tire Model Parameter Identification
Volume 3: 18th International Conference on Advanced Vehicle Technologies; 13th International Conference on Design Education; 9th Frontiers in Biomedical Devices, 2016The parameter values used in a tire model directly determine the prediction accuracy of the model. Poorly identified parameters lead to incorrect prediction of tire performances. The optimization algorithm used for parameter identification has a huge impact on the quality of the identified parameters for a tire model.

Vibration Analysis of a Tire Under Static Loading Using Flexible Ring-Based Model
Journal of Vibration and Acoustics, 2020Abstract To address various tire vibration characteristics such as noise, vibration, and harshness, it is necessary to study the tire dynamic performance. In this paper, we focus on investigating the influence of static loading on radial (in-plane) and bending modes and their frequencies of a tire.

Predictive Dynamic Model of a Deep Groove Ball Bearing With a Flexible Outer Ring
STLE/ASME 2008 International Joint Tribology Conference, 2008An explicit dynamic model of a deep groove ball bearing under a radial load is proposed. All components are treated as rigid bodies whereas the bearing outer ring flexibility is taken into account using fixed interface component mode synthesis (CMS).
