Accuracy analysis of a multi-loop linkage with joint clearances

Hybrid dimension reduction for mechanism reliability analysis with random joint clearances

“…The radii of the bearing and journal are different because of the clearance at the joint. The clearance circle [7][8][9][10][11][12][13] is defined as a circle with a radius of r c = r B − r J , where r B and r J are radii of the bearing and journal, respectively.…”

Robust tolerance design for function generation mechanisms with joint clearances

“…2, can be defined as the difference of the diameters of the pin and socket at a joint [15,[17][18][19]. When the continuous contact model assumption between the pin and socket at each joint is considered, the joint clearance can be modeled as a massless virtual link (clearance link) with the length equal to one half of the joint clearance.…”

A novel algorithm for kinematic and dynamic optimal synthesis of planar four-bar mechanisms with joint clearance

“…Most of the reported work was devoted to the analysis of linkages [5][6][7][8][9], while the reported work on the synthesis of linkages are more limited [10,11]. Ting et al [5] presented an approach to identify maximum errors due to the joint clearance.…”

“…Ting et al [5] presented an approach to identify maximum errors due to the joint clearance. Tsai and Lai [6] studied the effect of joint clearance on the accuracy of a multi-loop linkage. Innocenti [7] studied the effect of joint clearances in spatial mechanisms.…”
