Synthesis of clearance for a kinematic pair to prevent an overconstrained linkage from becoming stuck [PDF]
Mechanical Sciences, 2023 Mechanisms are prone to stuttering or even jamming due to the deformation of components, especially for overconstrained linkages for which geometric conditions must be strictly satisfied.

Numerical simulation of a model of vibrations with joint clearance [PDF]
International Journal of Computer Applications in Technology, 2008 Motivated by the problem of vibrations due to joint clearance between components in complex mechanical systems, we study in this paper the motion of a beam between rigid obstacles. We assume that the material is elastic and the motion is planar.

Translational Joints With Clearance in Rigid Multibody Systems [PDF]
Journal of Computational and Nonlinear Dynamics, 2007 A computational methodology for dynamic description of rigid multibody systems with translational clearance joints is presented and discussed in this work. Over the past years, extensive work has been done to study the dynamic effect of the revolute joints with clearance in multibody systems, in contrast with the little work devoted to model ...

Dynamic Response of Multibody Systems with Multiple Clearance Joints [PDF]
Journal of Computational and Nonlinear Dynamics, 2011 A general methodology for the dynamic modeling and analysis of planar multibody systems with multiple clearance joints is presented. The inter-connecting bodies that constitute a real physical mechanical joint are modeled as colliding components, whose dynamic behavior is influenced by the geometric, physical and mechanical properties of the contacting

Clearance of proteoglycan from joint cavities. [PDF]
Annals of the Rheumatic Diseases, 1987 The rate of loss from the synovial cavity of proteoglycan subunit, a major constituent of cartilage, has been measured in rabbits with and without experimental arthritis. The effect of aggregation between proteoglycan and hyaluronic acid upon the rate of elimination has also been investigated.
