ANALYTICAL CONDITIONS FOR MOTION
SWITCHABILITY IN A 2-DOF
FRICTION-INDUCED OSCILLATOR MOVING
ON TWO CONSTANT SPEED BELTS
ALBERT C. J. LUO AND TINGTING MAO
Abstract. In this paper, the analytical conditions are
presented for the nonsliding and sliding flows to the velocity
boundary in a 2-DOF friction-induced oscillator moving on two
constant speed belts. The mapping structures are introduced
and the periodic motions of the 2-DOF friction-induced
oscillator are presented through the corresponding mapping structure.
Velocity and force responses for stick and nonstick, periodic
motions in the 2-DOF friction-induced system are illustrated for
a better understanding of the motion complexity in multiple
degrees of freedom systems.
