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 ...

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 ...

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.

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
