Paper Abstract

An 8-bars linkage, formed by two four-bars and one slider-crank mechanisms connected in series, designed to obtain a rectilinear motion of the output link with two dwell periods, has been tested to validate the desired output motion. The input crank is powered, using a belt transmission, by an asynchronous motor fed by a voltage source inverter. The displacement in the dwells, measured with a Laser Doppler Vibrometer, has been recorded for different values of the input crank speed. By comparison to theoretical results it is shown that, for high input crank speed, link elasticity and joint clearances strongly influence the displacement amplitude in the dwells.
