平面棱柱铰内考虑摩擦效应的接触分析
Non-colliding contact analysis with friction in the planar prismatic joint
摘要
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 equa- tion is introduced based on the Coulomb's law of friction to make the problem solvable. The actual con- tact 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.关键词
