Abstract: Modeling and dynamic analysis of the narrow loom beat-up mechanism is presented. The equations of motion of the system are formulated considering the influence of the driver cam-follower mechanism as an improved analysis to an earlier study. Numerical results show the influence of the inertia forces due to the cam-follower mechanism. The model tends to account for the torsional and translational transmission of the cam-follower mechanism, the contact force of the roller/cam interface, the return spring force and the load acting on the cam-follower mechanism due to the action of the beater and all the damping, stiffness, mass and inertia of the mechanism components. The results illustrate that the system response decreases in magnitude as damping ratio increases in value. High peak values of the magnitudes are obtained at damping ratio <0.700 which is about the critical damping ratio for this type of system. The damping coefficient requirement for a reasonable control of the system could be obtained as illustrated by the steady state portion of the system response.
