Dynamic simulaion of multibody system with planar clearance joint

Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011
A tribological analysis scheme for multibody system with clearance joints is presented by integrating frictional contact model, wear calculation with multibody dynamics. Clearance joints are modeled as a continuous contact model with friction. Progressive wear process is simulated by a widely used a finite-element-based iterative scheme.

Constitutive Equations for Joints with Clearance

2005
The small displacements notion is widely used in tolerancing, particularly to describe the kinematics of joints with clearance. But this purely geometrical approach does not take into account the joint forces description. Our paper aims at examining the consequences of such an approach on the forces representation.

Analysis of clearance fit pin joints

International Journal of Mechanical Sciences, 1978
The 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.

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 ...

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.

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.

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,

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.

Kinematic Clearance Sensitivity Analysis of Spatial Structures With Revolute Joints (*)

Journal of Mechanical Design, 1999
The paper presents a new method to assess the influence of joint clearances in spatial structures that are composed of links connected by revolute joints. The method allows assessment of the amount by which joint clearances affect the rigid-body position of a generic link of the structure when an external load is exerted on the link.
