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 ...

Dynamics of Multibody Systems With Spherical Clearance Joints [PDF]
Journal of Computational and Nonlinear Dynamics, 2005 This work deals with a methodology to assess the influence of the spherical clearance joints in spatial multibody systems. The methodology is based on the Cartesian coordinates, with the dynamics of the joint elements modeled as impacting bodies and controlled by contact forces. The impacts and contacts are described by a continuous contact force model

Nonlinear Dynamic Behaviour of The Mechanisms Having Clearance and Compliant Joints [PDF]
International Journal of Advanced Design and Manufacturing Technology, 2022 In this paper, the rigid four-bar linkage with clearance joint has been examined. The effects of design parameters have been analyzed separately. Considering chaotic behaviour and undesirable vibrations of the system induced by joint clearance, it has ...

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.

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.

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.
