Contact Mechanics in Cylindrical Clearance Revolute Joints
Applied Mechanics and Materials, 2013A comparative study concerning the dynamics of chain drives mechanisms is presented in this article. The study compares the dynamic response using the spherical contact model proposed by Lankarani and Nikravesh with a new enhanced cylindrical model developed by the authors to describe the contact phenomenon in cylindrical clearance revolute joints.

Wave Motion Dynamic Analysis of Planar Frame Structures With Clearance Joints
, 2021Due to kinematic function requirements, deployable structures inevitably have many clearance joints. The existence of clearance joints not only reduces the structural stiffness but also leads to complex nonlinear dynamic characteristics.

Identifying joint clearance via robot manipulation
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2017Inaccuracy in robot manipulation is a result of various uncertainties. Most methods reduce operation errors by calibrating robot parameters, with little attention on understanding the uncertainty sources in the process. This paper investigates how operation accuracy of robot manipulators can be improved by identifying one of the major uncertainty–joint

Inadequate clearance can affect weld quality and efficiency. In extreme cases, obstructions may cause a lack of fusion between the base metal and the weld metal, causing a reduction in strength. Although flux cored arc welding (FCAW) and gas metal arc welding (GMAW) have replaced shielded metal arc welding (SMAW) as the primary fabrication processes ...

Analysis of clearance fit pin joints
International Journal of Mechanical Sciences, 1978The analysis of clearance fit joints falls within the realm of mixed boundary problems with moving boundaries. In this paper, this problem is solved by a simple continuum method of analysis applying an inverse technique; the region of contact is specified and the corresponding causative load is evaluated.

Pin-slot clearance joints in multibody systems
International Journal of Precision Engineering and Manufacturing, 2017The pin-slot joint is one of the most commonly used form of kinematic pairs, which with clearance will have a significant effect on the motion and dynamic response of multibody systems. In this study, the multibody system with a pin-slot clearance joint is modeled and the kinematic and dynamic effects are studied.
