Modeling of a linear motor feed drive including pre-rolling friction and aperiodic cogging and ripple
(Springer, 2014-04)
This work addresses the systematic modeling of a linear feed drive based on a linear synchronous motor, a helpful step in control design for precise machine tools using linear motors. The model considers the electrical ...
On Lugre Friction Model to Mitigate Nonideal Vibrations
(Asme-amer Soc Mechanical Eng, 2009-07-01)
In this paper, a nonideal mechanical system with the LuGre friction damping model is considered. The mechanical model of the system is an oscillator not necessarily linear connected with an unbalanced motor of excitation ...

Modelling an Inertia Wheel Pendulum Benchmark
(Taylor & Francis, 2005-09)
In this paper, modelling and parameter identification of an inertia wheel pendulum benchmark is considered. This is an underactuated mechanical system useful for teaching and research. Attention is focused on deriving a ...
Influence of Potential Shape on Constant-Force Atomic-Scale Sliding Friction Models
(Springer, 2015-11)
The majority of atomic-scale friction models inwhich sliding is proposed to occur over the atomic-scaleenergy corrugation at the sliding interface assume a simplesinusoidal potential. An analysis of these models showsthat ...
Computational modeling of 2D frictional contact problems based on the use of coupling finite elements and combined contact/friction damage constitutive model
(2022-02-01)
This work proposes a new approach to describe 2D frictional contact problems based on the use of coupling finite elements (CFEs) and a combined contact/friction damage constitutive model. This technique is able to establish ...
An implicit/explicit integration scheme to increase computability of non-linear material and contact/friction problems
(Elsevier Science Sa, 2008-12)
An implicit/explicit integration scheme for non-linear constitutive models is presented. It aims at providing additional computability to those solid mechanics problems were robustness is an important issue, i.e. material ...
Numerical simulation of the lubricant performance
(Elsevier Science Sa, 2008-03)
Due to the high pressures that are involved in tube hydroforming processes, high values of the friction forces are developed and, therefore, lubricants are usually employed to increase the formability of the workpiece. ...
Modeling of thermal cycles and microstructural analysis of pipeline steels processed by friction stir processing
(2018-10-01)
During friction stir welding or processing (FSP), temperature and deformation have influence on the final microstructure and mechanical properties. Studying microstructures before and after welding might help interpreting ...
