effect of bifurcation and chaos on the functioning of mechanical systems with clearance
Many rotor systems are subjected to complex response patterns
due to various nonlinearities in the system. These
nonlineatities are in the form of clearance and or friction.
A comprehensive dynamic behavior characterization of such
systems becomes increasingly important such that a practicing
engineer or a designer is well aware of all the possible
motions that the system can exhibit during the course of
their operation. This research is aimed at developing a
problem independent analysis tool for identifying regimes of
complex nonlinear behavior that strongly nonlinear problems
are capable of displaying. The three systems that are
studied in this research are (1) Single degree of freedom
clearance type nonlinear oscillator that is a representation
of the generic model of a gear pair interaction (2) Rolling
element bearing system with combined parametric excitation,
clearance type nonlinearity and nonlinear Hertzian type
contact forces and (3) Rotor with unbalance mass mounted on
supports with clearance. The presence of complex behavior
like chaos in a clearance type nonlinear system is
demonstrated through an experimental investigation of a
"Major Subject: Mechanical Engineering".
