Stabilizing slider-crank mechanism with clearance joints
Mechanism and Machine Theory, 2012Abstract In general, in dynamic analysis of mechanical systems, joints are assumed to be ideal without clearance. When joint clearance is introduced, dynamic response is considerably changed. Degradation of dynamic performance, reduction in components fatigue life and generation of undesirable vibrations result from impacts of mating parts in ...

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.

Total Joint Arthroplasty: Should Patients Have Preoperative Dental Clearance?
The Journal of Arthroplasty, 2014Obtaining dental clearance prior to elective total joint arthroplasty is a common practice; however, little published data exist to justify this requirement. Dental clearance data for 365 elective total knee and total hip arthroplasty patients were gathered prospectively.

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 ...

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.

Joint Mexico-US customs clearance would ease trade
Emerald Expert Briefings, 2023Significance While the full modernisation plan has not yet been unveiled, it will probably represent the largest joint infrastructure investment in decades and could further cement bilateral ties. Impacts The Biden administration may struggle to prevent US ...

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.

Accuracy Analysis of Parallel Manipulators With Joint Clearance
Journal of Mechanical Design, 2008Due 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.

Dynamic analysis of a planar multibody system with multiple revolute clearance joints
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2019This paper focuses on the dynamic responses of a planar mechanism with multiple clearance joints. The effect of the impact between the journal and the bearing in the clearance joint is described using an improved impact force model, and a typical four ...
