| Abstract: |
| The frictional contact analysis without impact in the planar prismatic joint of multi-body systems is studied in this paper.The corresponding contact forces are obtained from the equivalence of the contact forces and joint reaction force,and finally lead to a linear complementary equation in terms of the resultant frictional force based on the complementary conditions between themselves.An additional equation is introduced based on the Coulomb’s law of friction to make the problem solvable.The actual contact situation is obtained from the contact forces.The instants of switching from one situation to another can be also captured using the method proposed in this paper,and it is verified in ADAMS that the very instants are the impact instants.This provides a high-efficient way to study the impact effects in joints. |
