Abstract EN
Translational and revolute joints are the main kinds of joints in planar multilink mechanisms.
Translational and revolute clearance joints have great influence on dynamical responses of planar mechanisms.
Most research studies mainly focused upon revolute clearance of planar mechanisms based upon the modified Coulomb friction model, some studies investigated clearance of the pin-slot joint, and few studies researched mixed clearances (considering both translational clearance and revolute clearance) based on the LuGre friction model.
Dynamic response of the 2-DOF nine-bar mechanism considering mixed clearances based on the LuGre model is investigated in this work.
The dynamic model with mixed clearances is built by the Lagrange multipliers.
Dynamic responses including motion output of the slider, driving torques, contact forces, shaft center trajectories at revolute clearance pairs, and slider trajectory inside the guide are analyzed, respectively.
Influences of different friction models on dynamic responses are studied, such as LuGre and modified Coulomb’s friction models.
Effects of different clearance values and different driving speeds on dynamic responses with mixed clearances are both analyzed.
Virtual prototype model considering mixed clearances is carried out through ADAMS to verify correctness.
