Translational Joints With Clearance in Rigid Multibody Systems [PDF]
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]
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

Numerical simulation of a model of vibrations with joint clearance [PDF]
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.

Nonlinear Dynamic Behaviour of The Mechanisms Having Clearance and Compliant Joints [PDF]
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 ...

Dynamic Response of Multibody Systems with Multiple Clearance Joints [PDF]
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

Synthesis of clearance for a kinematic pair to prevent an overconstrained linkage from becoming stuck [PDF]
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.
