Generalized high-speed vibration-damping transfer cam curve with arbitrary rise time in point symmetry consisting of half-odd-integer trigonometric functions

Abstract: In the present investigation, we have proposed universal formulas for point symmetrical high-speed vibration-damping transport cams for a 1DOF undamped follower vibrator in an arbitral rise ...
