Joint bearing, spherical plain bearing) has two "joint" of spherical surface contact, the contact is called a coordination of contact.Joint bearing mechanical characteristics calculation method for structure design of joint bearing and wear analysis plays an important role.Coordinate surface contact pressure calculation is a very complicated problem, existing Hertz model due to the limited to the elastic half space body, cannot be used for calculation of spherical coordinate contact pressure distribution.Already have a spherical contact unified model, namely, Fang model, can well solve the problems of the small deformation of spherical contact pressure distribution, the model for the coordination of contact and coordination are applicable.But not complete spherical joint bearing contact area, the calculation of the contact pressure distribution needs to complete in spherical coordinate contact model on the basis of the further calculation.In addition, the use of joint bearing will also appear in the process of free boundary effect, which will have an impact on the application of joint bearing.Free boundary effect on the edge of the joint bearing outer ring contact stress concentration and large pressure gradient.
