Modeling of joints with clearance in flexible multibody systems

International Journal of Solids and Structures, 2001
Abstract This paper is concerned with the modeling of joints with clearance within the framework of finite element based dynamic analysis of nonlinear, flexible multi-body systems. For actual joints, clearance, lubrication and friction phenomena can significantly affect the dynamic response of the system.

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 ...

Dynamics of Mechanisms With Slider Joints and Clearance

Volume 6B: 18th Biennial Conference on Mechanical Vibration and Noise, 2001
Abstract In this study a planar mechanism with a rotating sliding joint is investigated. Periodic behavior is observed for zero clearance of the sliding joint. The sliding joint with clearance is modeled using a kinematic coefficient of restitution and a coefficient of friction.

Effect of Bearing Clearance on Cardan-Joint Kinematics

15th Design Automation Conference: Volume 3 — Mechanical Systems Analysis, Design and Simulation, 1989
Abstract The effect of radial bearing clearance at the intermediate joints of a Cardan-type universal joint has been investigated. It is found that errors in displacement at the output and also intermediate joints occur, and that their amplitudes have a linear relationship to the magnitudes of the radial bearing clearances.

Uncertainty Analysis of Planar Robots With Joint Clearance

Volume 5: 6th Flexible Assembly Conference, 1998
Abstract Joint clearance in mechanisms and robots leads to uncertainty in function deviation. Unlike the impact of the link tolerance on the performance quality, the uncertain effect of the joint clearance to the performance can not be eliminated by calibration because of the random nature. In this paper, based on the probability theory,

Multi-objective Optimization of Mechanisms with Clearances in Revolute Joints

2014
Despite extensive work on the evaluation of the dynamic performances of various mechanisms and multi-body mechanical systems with revolute joint clearances, limited work has been conducted in optimizing the performances of these systems. A multi-objective optimization technique is presented to examine and to quantify the effect of combined objective ...

Analysis and experimental study of the spherical joint clearance

SPIE Proceedings, 2013
The spherical joint clearance is a key error factor, which influenced and restricted the application of parallel mechanism in high precision field. This paper discusses the regularity of the spherical joint clearance in the parallel mechanism and its influence on the accuracy of the parallel mechanism in both theoretical and experimental aspects.

Accuracy Analysis of Parallel Manipulators With Joint Clearance

Journal of Mechanical Design, 2008
Due to joint clearance, a parallel manipulator’s end-effector exhibits position and orientation (or collectively referred to as pose) errors of various degrees. This paper aims to provide a systematic study of the error analysis problem for a general parallel manipulator influenced by joint clearance.
