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.
