Cam Functions That Simultaneously Suppress Two Vibration Modes in 2DOF Undamped Oscillator for Rest-to-Rest Motion

Abstract

In this study, from the definition of vibration manipulation function (VMF), we have derived residual-vibration-suppressed cam function for rest-to-rest motion of an undamped 2DOF oscillator by appropriately selecting the rising time of cam. At first, we utilized VMF to induce residual-vibration-suppressed cam function for an undamped 1DOF oscillator regardless of the rising time. In following stage, by numerical calculation, we determined some specific rising times of cam that can perform rest-to-rest motion for undamped 2DOF oscillator without residual vibration. The obtained cam function was a non-halting high-speed cam.
