Problems with Coulomb Damping

Question asked by Pranav Nalawade on May 8, 2020

I am trying to do a motion analysis for this pawl pusher mechanism. Currently the problem I'm having is that there seems to be almost negligible friction damping, leading to the pawls pushing the basket to and fro. I have calculated the spring stiffness based on the reaction that should be developed by the basket but it only seems to work when it is much lower than calculated or if i add a separate linear damper. I have checked the friction values but i cant seem to find any errors. what might be wrong? do I need to add a separate linear damper? If yes, how to determine its value. thanks
