If you model the part with generalized plane strain elements, you must use the Keywords Editor to apply boundary conditions on the active degrees of freedom (U3, UR1, and UR2) at the reference node of these elements (see Adding unsupported keywords to your Abaqus/CAE model).
To edit an existing base motion boundary condition using menus or managers, see Editing step-dependent objects. In the Basic tab, select the Degree-of-freedom to specify the direction for which the base motion is being defined. This direction is always a global direction: U1, U2, U3, UR1, UR2, or UR3. So if you define a cylindrical coordinate system, at a particular point U2 = tangential displacement, UR3 = rotation about local "z" axis (axis that runs throught the point of interest and is parallel to the cylindrical coordinate system axis).
Toggle on the buttons labeled U1, U2, and U3 to constrain the end of the hinge in the 1-, 2-, and 3-directions. You do not need to constrain the rotational degrees of freedom of the hinge because solid elements (which have only translational degrees of freedom) will be used to mesh the hinge.
Antisymmetry about a plane with X = constant (U 2 = U 3 = UR 1 = 0; Abaqus/Standard only). YASYMM. Antisymmetry about a plane with Y = constant (U 1 = U 3 = UR 2 = 0; Abaqus/Standard only). ZASYMM. Antisymmetry about a plane with Z = constant (U 1 = U 2 = UR 3 = 0; Abaqus/Standard only). PINNED. Pinned (U 1 = U 2 = U 3 = 0). ENCASTRE course, and in principle ABAQUS should be able to find them, but it is not coded to do so. To demonstrate that this is the cause of the problem, in the Load module create a new BC that will constrain the displacements on the inner surface of the lowest hole in the wheel (see the figure). Prescribe a displacement U1=U3=0, U2= - 0.005. Then return to
Abaqus ignores them. If your model is anything similar to figure 3.10 (your attachments), then the boundary conditions at the bottom edge are U1=0, U2=0 and U3=0 ( your Y axis is vertical). All
