Abstract: With the new improvements in the fuel economy engines and to enhance the passenger’s comfort, the topic of active vibration cancellation has received a lot of attention recently by both the ...

Abstract: In this paper, the dynamics of a one-degree-of-freedom mechanical positioning device with nonlinear stiffness and linear feedback are described. Experimental results show that chaotic dynamics can ...

Abstract: Lead screw mechanisms are used to convert rotary to linear motion. The velocity-dependent coefficient of friction at the contact between lead screw and nut threads can lead to self-excited ...
