A Comparative Study of Joint Clearance Effects on Dynamic Behavior of Planar Multibody Mechanical Systems

open access: yesLatin American Journal of Solids and Structures
Clearance always exists in actual joint due to many uncertainties such as machining tolerance, assemblage and load deformation. The main purpose of this paper is to propose a computational and experimental study on the dynamic characteristics of a planar

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

open access: yesMechanical 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.

Translational Joints With Clearance in Rigid Multibody Systems [PDF]

open access: yesJournal 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]

open access: yesJournal 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

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

open access: yesInternational 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.

Experimental investigations of the dynamic responses of a multi-link mechanism with revolute clearance joints

open access: yesAdvances in Mechanical Engineering, 2021
Joint clearance is unavoidable in the revolute joint of multi-link mechanism. Excessive value of joint clearance generally leads to the noise, vibration, and fatigue failure.

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

open access: yesJournal 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
