In traditional methods, the details of relative motion
between two bodies is necessary to locate contact points. When they are
applied to analyze the contact in a joint, the bodies linked by the joint
must be taken as free, no matter how small the clearance of the joint is. As
a result, such drawback makes numerical solution inefficient and inaccurate
in some cases. It is found that, the system of contact forces in a joint and
the system of constraint reaction forces of the joint are equivalent, and
the motion of possible contact points in joint relate each other inherently.
Based on these facts, this paper present a method for frictional contact
analysis of spatial prismatic joints, by which the positions and forces of
contacts can be obtained while the kinematic constraints of prismatic joints
are kept. Numerical examples prove the validity of the method.
