Revolute joints with clearance in multibody systems

Paulo Flores, +1 more
- 01 Jul 2004 - 
TL;DR: In this paper, a computational methodology for dynamic analysis of multibody mechanical systems with joint clearance is presented, based on a thorough geometric description of contact conditions and on a continuous contact force model, which represents the impact forces.
Journal ArticleDOI

A study on dynamics of mechanical systems including joints with clearance and lubrication

Paulo Flores, +4 more
- 01 Mar 2006 - 
TL;DR: In this paper, a methodology for the dynamical analysis of mechanical systems considering realistic joint characteristics, namely, joints with clearance and lubrication, is presented, in which the energy dissipation in form of hysteresis damping is considered.
Journal ArticleDOI

Dynamic Analysis for Planar Multibody Mechanical Systems with Lubricated Joints

Paulo Flores, +2 more
- 01 Aug 2004 - 
TL;DR: The dynamic analysis of planar multibody systems with revolute clearance joints, including dry contact and lubrication effects is presented here, and a general methodology for modeling lubricated revolute joints in multibODY mechanical systems is presented.
Journal ArticleDOI

Numerical and experimental investigation on multibody systems with revolute clearance joints

Paulo Flores, +4 more
- 01 Sep 2011 - 
TL;DR: In this paper, a combined numerical and experimental study on the dynamic response of a slider-crank mechanism with revolute clearance joints is presented and discussed to provide an experimental verification and validation of the predictive capabilities of the multibody clearance joint models.
Journal ArticleDOI

On the contact detection for contact-impact analysis in multibody systems

Paulo Flores, +1 more
- 20 May 2010 - 
TL;DR: In this paper, the authors present a general and comprehensive approach to automatically adjust the time step, in variable time-step integration algorithms, in the vicinity of contact of multibody systems.
