Vibration of a Flexible Follower in a Cam Mechanism with Time-Dependent Boundary Effect

A vibration analysis of a flexible follower in an oscillating cam system undergoing rise-dwell-fall-dwell (RDFD) motion is performed. Owing to the time-dependent boundary effect caused by considering simultaneously axial and lateral displacements follower, two geometric constraints are formulated added Hamilton’s principle establish equation follower. The coupled has been studied for first time. fast Fourier transform (FFT) spectrum generated from time history used parametric studies. numerical results present study show some new findings. major spectral peaks response locate at low frequencies 1 Ω, 3 5 7 Ω high frequency near fundamental natural where speed. largest peak locates mostly Ω. For ascending descending motions RDFD motion, three types profiles designed. Important found: although nearly overlap, quite different. By using modified sinusoidal acceleration magnitude main minimized. amplitude smallest when cycloid displacement adopted.
