Identifying joint clearance via robot manipulation

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2017
Inaccuracy 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

Clearance for Welded Joints

Engineering Journal, 2019
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 ...

Contact Mechanics in Cylindrical Clearance Revolute Joints

Applied Mechanics and Materials, 2013
A 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.
