Evaluation of Joint Clearance Effects on the Shimmy of Nose Landing Gear

Aerospace, 2023
Through the establishment of a three-dimensional joint clearance model, the effects of joint clearances at different positions on shimmy stability are evaluated. In this paper, considering the radial, axial and coupling characteristics of joint clearance,

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

Scientific 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

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

International 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.

Study on Wear Characteristics of Revolute Clearance Joints in Mechanical Systems

Micromachines, 2022
The existence of clearance causes contact-impact forces in joints, which lead to surface wear and incessant material loss of the joint surface during the motion of mechanisms.

Revolute joints with clearance in multibody systems [PDF]

Computers & 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.
