Dynamic Response of Multibody Systems with Multiple Clearance Joints [PDF]

open access: yesJournal of Computational and Nonlinear Dynamics, 2011
A general methodology for the dynamic modeling and analysis of planar multibody systems with multiple clearance joints is presented. The inter-connecting bodies that constitute a real physical mechanical joint are modeled as colliding components, whose dynamic behavior is influenced by the geometric, physical and mechanical properties of the contacting

Dynamics and Wear Prediction of Mechanisms Considering Multiple Clearances and Coatings

open access: yesLubricants, 2023
The increase in joint clearance and system vibration caused by joint wear are important factors that may lead to the failure of the mechanism and a decrease in the motion accuracy of the actuator.

Dynamic response analysis for multi-degrees-of-freedom parallel mechanisms with various types of three-dimensional clearance joints

open access: yesInternational Journal of Advanced Robotic Systems, 2021
For spatial multibody systems, the dynamic equations of multibody systems with compound clearance joints have a high level of nonlinearity. The coupling between different types of clearance joints may lead to abundant dynamic behavior.

Nonlinear Dynamics and Control of Crank-Slider Mechanism with Multiple Clearance Joints [PDF]

open access: yesJournal of Theoretical and Applied Vibration and Acoustics, 2015
In the current study, behavior of crank-slider mechanism with single and multiple clearance joints are analyzed. Using Lankarani-Nikravesh theory for estimating discontinuous contact forces in clearance joints, relevant systems have been mathematically ...

Antibiotics with Interleukin-15 inhibition reduces joint inflammation and bone erosions but not cartilage destruction in Staphylococcus aureus-induced arthritis [PDF]

open access: yes, 2018
Background: Staphylococcus aureus-induced arthritis causes rapid joint destruction, often leading to disabling joint damage despite antibiotics. We have previously shown that IL-15 inhibition without antibiotics is beneficial in S.

Effect of Multi-Joint Clearance Coupling on Shimmy of Nose Landing Gear

open access: yesAerospace, 2023
The existence of joint clearances in the nose landing gear (NLG) is inevitable and significantly affects shimmy. It was found that the interaction of each joint clearance is closely related to the analysis of shimmy stability.

Bone-to-bone and implant-to-bone impingement : a novel graphical representation for hip replacement planning [PDF]

open access: yes, 2020
Bone-to-bone impingement (BTBI) and implant-to-bone impingement (ITBI) risk assessment is generally performed intra-operatively by surgeons, which is entirely subjective and qualitative, and therefore, lead to sub-optimal results and recurrent ...

Sensitivity Analysis for Optimal Design of Multibody Systems with Clearance Joint [PDF]

open access: yesInternational Journal of Advanced Design and Manufacturing Technology, 2018
This paper deals with the sensitivity analysis and optimization of system parameters for a classical slider-crank mechanism as a multibody system which includes a clearance between the joints of coupler and slider. Due to the nonlinearity involved in the
