Routes To Chaos In Ball Bearings

Effect of Radial Internal Clearance of a Ball Bearing on the Dynamics of a Balanced Horizontal Rotor

“…In the present study for an SKF6002 ball bearing the radial internal clearance is taken as the main parameter of study, which has not been reported by Fukata [4], Mevel and Guyader [5] and Sankaravelu [6].…”

“…We see that G is a function of time and this imparts the parametric e!ect to the system. The damping in this system is represented by an equivalent viscous damping C. The value of the damping depends on the linearized bearing sti!ness (5). The value of the damping has been estimated ( Table 1).…”

“…It is a more detailed analysis as compared to Sunnerjo's [3] work as regimes of super-harmonic, sub-harmonic and chaotic behavior are found out. Mevel and Guyader [5] have developed a theoretical model of a ball bearing supporting a balanced horizontal rigid rotor, with a constant vertical radial force. This is similar to the work done by Fukata et al [4] but more results have been reported for parametric studies undertaken and routes to chaos traced out.…”

Dynamic Response of an Unbalanced Rotor Supported on Ball Bearings

“…For a horizontal Je!cott rotor supported on ball bearings the exciting frequencies are because of the unbalance force and the varying compliance e!ect. The combined e!ect of unbalance and varying compliance has not been considered by Fukata [1], Mevel and Guyader [2] and Sankaravelu [3]; in these works only the varying compliance e!ect is considered. The inclusion of the unbalance force makes the system biperiodically excited.…”

Nonlinear vibration signature analysis of a rotor supported ball bearings

“…Both Perret and Meldau performed a quasi-static analysis since inertia and damping force were not taken into account. Mevel and Guyader (1993) have developed a theoretical model of a ball bearing supporting a balanced horizontal rigid rotor, with a constant vertical radial force. This is similar to the work done by Fukata et al (1985) but more results have been reported for parametric studies undertaken and routes to chaos traced out.…”
