Revolute joints with clearance in multibody systems [PDF]
Computers & Structures, 2004 A computational methodology for dynamic analysis of multibody mechanical systems with joint clearance is presented in this work. Clearances always exist in real joints in order to ensure the correct relative motion between the connected bodies being the gap associated to them a result of machining tolerance, wear, and local deformations.

NUMERICAL CALCULUS REGARDING THE MOTION BEHAVIOUR [PDF]
Fiabilitate şi Durabilitate, 2012 The kinematic links motion is influenced mostly by the clearance size from the joint and the number of joints with clearance. The presented paper studies a particular kinematic chain as physical pendulum with clearance.
