Analysis of the joint clearance effects on a compliant spatial mechanism
Mechanism and Machine Theory, 2016 This study investigates the dynamics of a partly compliant mechanism with joint clearance. A spatial slider-crank mechanism is used as a numerical example.

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 ...

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, 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.

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.
