Chaotic behaviour exhibited during contact loss in a clearance joint of a four-bar mechanism

Investigation on the Dynamic Performance of the Tripod-Ball Sliding Joint With Clearance in a Crank–slider Mechanism. Part 1. Theoretical and Experimental Results

“…However, the initial conditions were found to in#uence strongly the dynamic behavior of the mechanism during the "rst few cycles [9]. Extensive computer runs show that, if the simulation is allowed to continue over a large number of cycles, then a quasi-steady state may happen.…”

The Non-Linear Dynamic Behavior of an Elastic Linkage Mechanism With Clearances

“…Although the dynamic modelling work for the elastic linkage mechanism with clearance connections has attracted more and more attention and gained some achievements, the non-linear behavior analysis caused by joint clearances has only been analyzed initially in the literature [16] and has not been carried out widely. The alternative change of contact, impact and loss of contact in the elastic linkage mechanism with clearances is equivalent to a piecewise linear system belonging to non-linear dynamic systems.…”

Accuracy analysis of a multi-loop linkage with joint clearances

“…The research on the joint clearance can be roughly divided into two groups. One considered only partial joint clearances in a mechanism [9][10][11][12][13][14][15][16][17][18][19]. The other considered the effects of all joint clearance in a mechanism [20][21][22].…”
