Modeling of joints with clearance in flexible multibody systems
International Journal of Solids and Structures, 2001Abstract 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.

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, 2001Abstract 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.

Dynamic response of a revolute joint with clearance
Mechanism and Machine Theory, 1996The response of a revolute joint in a four-bar mechanism with a clearance is investigated. Motion of a rocker-arm pin at the ground connection is modelled using a Lagrangian approach. When the resulting equations of motion are solved numerically, they show non-linear dependence on both the size of the clearance and the coefficient of friction between ...

Method for measuring clearances in precision joints
Measurement Techniques, 19641. This instrument can be used in combination with an actuating device for effective control in fitting diameters of one of the conjugate components to the other by a method similar to that described in [3] or [4]. 2. The design of the clearance testing instrument (see Figure) provides the possibility of testing the clearance (or fit ...

Constitutive Equations for Joints with Clearance
2005The 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.

To model joints with clearance for tolerance analysis
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2014Mechanical products are usually made by assembling many parts. Among the different types of links, bolts are widely used to join the components of an assembly. In a bolting, a clearance exists among the bolt and the holes of the part to join. This clearance has to be modelled in order to define the possible movements agreed to the joined parts.
