MINIMIZING RESIDUAL VIBRATIONS IN HIGH-SPEED CAM-FOLLOWER SYSTEMS OVER A RANGE OF SPEEDS

A direct procedure, based on the generalized Lagrange multiplier metho d, will be presented for designing high-speed cam-follower systems ove r a range of cam speeds. With this method residual vibrations at the e nd of the rise of a Dwell-Rise-Dwell (DRD) cam motion are minimized fo r any specified range of rise times. A minimum of boundary conditions on the cam displacement function will be specified to reduce unnecessa ry constraints on the cam displacement function. The applicability of rules of thumb generally accepted in designing for minimum vibrations will be discussed and compared to the results from this approach.
