Error estimation and compensation in 4R and P3R closed-chain mechanisms due to joint clearance: a comparative study [PDF]

open access: yesScientific Reports
Four-bar linkages form the fundamental configuration of many planar mechanisms, and joint clearance is one of the primary factors that introduce deviations from their intended output. This paper presents a performance assessment of planar mechanisms with

Lead-Screw-Driven Revolute Joint for Use in the Remote Center of Motion Mechanism

open access: yesIEEE Access, 2022
The revolute joint of the remote center of motion (RCM) mechanism should be operated within a limited rotation range to ensure patient safety. To achieve this with the conventional revolute joint, the rotation range was limited with the use of software ...

A Study on Dynamic Characteristics of Satellite Antenna System considering 3D Revolute Clearance Joint

open access: yesInternational Journal of Aerospace Engineering, 2020
Clearances in the joints of real mechanisms are unavoidable due to assemblage, manufacturing errors, and wear. The dual-axis driving and positioning mechanism is one kind of space actuating mechanism for satellite antenna to implement precise guidance ...

Revolute joints with clearance in multibody systems [PDF]

open access: yesComputers & Structures, 2004
A computational methodology for dynamic analysis of multibody mechanical systems with joint clearance is presented in this work. Clearances always exist in real joints in order to ensure the correct relative motion between the connected bodies being the gap associated to them a result of machining tolerance, wear, and local deformations.

On the Dependency of the Electromechanical Response of Rotary MEMS/NEMS on Their Embedded Flexure Hinges’ Geometry

open access: yesMicromachines, 2023
This paper investigates how the electromechanical response of MEMS/NEMS devices changes when the geometrical characteristics of their embedded flexural hinges are modified. The research is dedicated particularly to MEMS/NEMS devices which are actuated by

Numerical and experimental study on dynamics of the planar mechanical system considering two revolute clearance joints

open access: yesInternational Journal of Mechanical System Dynamics, 2021
Due to assembly, wear and manufacturing errors and clearance in the joints are inevitable. When the clearance is introduced into a mechanical system, the impact force in the clearance joint will cause undesirable vibration of the system.

3D Formulation for Revolute Clearance Joints [PDF]

open access: yes, 2016
In this work, a general and comprehensive methodology for the modeling and analysis of spatial multibody systems with revolute clearance joints is presented. The proposed formulation considers the journal and the bearing elements as two cylindrical colliding bodies.
