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.

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.

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 ...

Accuracy Analysis of General Parallel Manipulators with Joint Clearance
Proceedings 2007 IEEE International Conference on Robotics and Automation, 2007Due to the joint clearance, parallel manipulators always exhibit some position and orientation errors at the mobile platform. This paper aims to provide a systematic framework for the error analysis problem of general parallel mechanisms influenced by the joint clearance.

Modeling 3D revolute joint with clearance and contact stiffness
Nonlinear Dynamics, 2011The clearances in the kinematic joints are due to deformations, wear, and manufacturing errors; the accurate modeling of these effects in multibody analysis is a complex issue but in many practical applications, it is mandatory to take into them into account in order to understand the actual behavior of mechanical systems.

Dynamic simulaion of multibody system with planar clearance joint
Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011A 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
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.
