Features testedAutomatic shrink fit Small-sliding contact pair Problem descriptionThe models consist of elements with their contact surfaces initially overclosed. This initial overclosure is removed in the first step, which is nonlinear. The second step is a linear perturbation step, wherein relative sliding is performed between the two surfaces. The value of friction is changed in the third nonlinear step. The fourth step is a linear perturbation step, wherein relative frictional sliding is performed between the two surfaces. The fifth step is a direct-solution steady-state dynamic analysis of the two surfaces in contact. In the sixth step the natural frequencies are extracted, which are then used in the seventh step to conduct a subspace-based steady-state dynamic analysis. A five-step test is carried out for generalized axisymmetric elements. Anisotropic friction is used throughout the test. The first and second steps are the same as mentioned earlier. The third step is a linear perturbation step, wherein relative twisting is performed between the two surfaces. Steps 4 and 5 are similar, except that Step 4 is a linear perturbation step. In these steps both relative sliding and twisting are performed between the two surfaces. Only a four-step test is carried out for cylindrical-type elements. Model:
