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. 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). A list of the boundary conditions used in ABAQUS. U1, U2 and U3 specify movements along Table 1. UR2 and UR3 specify rotation about the x, y and z axes, respectively. 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. XASYMM Antisymmetry about a plane with X = constant (U2 = U3 = UR1 = 0;ABAQUS/Standard only). YASYMM Antisymmetry about a plane with Y = constant (U1 = U3 = UR2 = 0;ABAQUS/Standard only). ZASYMM Antisymmetry about a plane with Z = constant (U1 = U2 = UR3 = 0;ABAQUS/Standard only). PINNED Pinned (U1 = U2 = U3 = 0). • In the boundary condition module constrain U1, U2, U3 at the entire bottom of the part to zero. Apply a displacement of U1= -0.00254 on the other end of the part. • Create a job and submit and run it (it will take some time to complete, as the mesh has 30000 quadratic elements). 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 ABAQUS Scripting Reference Manual u1. A Float, a Complex, or a SymbolicConstant specifying the displacement component in the 1-direction. Note: Although u1, u2, u3, ur1, ur2, and ur3 are optional arguments, at least one of them must be specified. u2. A Float, a Complex, or a SymbolicConstant specifying the displacement component in the 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). 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 W250nG.
