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 ...

Effects of joint clearance on the dynamics of a partly compliant mechanism: Numerical and experimental studies

Mechanism and Machine Theory, 2015
Compliant mechanism has got at least one flexible member between conventional rigid links. It is a good choice for decreasing the number of movable joints and also their clearance effects.

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.

Experimental investigation of joint clearance effects on the dynamics of a slider-crank mechanism

Multibody System Dynamics, 2010
Clearance is inevitable for assembly and mobility in the kinematic joints of mechanisms. Excessive value of this clearance leads to poor operational characteristics, and these result in losses in kinematic and dynamic performances of mechanism.
