The normal problem solution gives: – the distribution of opening and closing zones (contact areas); – the distribution of normal nodal forces; – the node openings at the joint plane; – the coefficient a and the angle α of rigid body displacement of the cap. It is assumed that the contact area and the maximum force on the joint plane as well as the hydrodynamic pressure forces at the film level are known. The displacement of the nodes in axial direction z is assumed to be insignificant. 16] where (i) and y1(i) and (i) are the normal and tangential components of the force on node i, are the tangential displacements of node i, respectively, for the current and the previous load, y1(P(i)) and are the tangential displacements of the node i projection on surface 2, respectively, for the current and the previous load and KTi is the penalty coefficient similar to a tangential stiffness at node i.

5]. The last is always less than the adhesion coefficient. It is worth noting that unlike the normal problem, the solution to the tangential problem depends on the load history. Following the same approach as with the normal components, the following expressions can be written as: where Cb represents the y displacement component of the rigid solid at the cap. It must be noted that the displacement along y does not depend on the rotation of the rigid solid at the cap as the joint plane is located at x = 0.

Until the late 1960s, there were few drivers who had not “thrown out a rod”.
