*KINEMATIC COUPLING

11.3 *KINEMATIC COUPLING: Constrain all or speciﬁc degrees of freedom of a set of

nodes to the rigid body motion of a reference node.

This option is used to impose constraints between degrees of freedom of a node or node set and the rigid body

motion deﬁned by a reference node. The pre ferred method of providing a kinematic constraint of this type is

the *COUPLING option used in conjunction with the *KINEMATIC option.

Product: ABAQUS/Standard

Type: Model data

Level: Part, Part instance, Assembly

Reference:

•“Kinematic constraints: overv iew,”Section 28.1.1 o f the ABAQUS Analysis User’s Manual

Required parameter:

REF NODE

Set this parameter equal to either the node number of the reference node or the nam e of a node set

containingthe reference node. Ifthe name of a node set is chosen, the node set must containexactly

one node.

Optional parameter:

ORIENTATION

Set this parameter equal to the name given to the *ORIENTATION deﬁnition (“Orientations,”

Section 2.2.5 of the ABAQUS Analysis User’s Manual) that speciﬁes t he initial orientation of the

local system in which the constrained degrees of freedom are deﬁned.

Data lines to specify the nodes and degrees of freedom to be constrained:

First line:

1. Nodenumber or node set label.

2. First degree of freedom constrained. See “Conventions,” Section 1.2.2 of the

ABAQUS Analysis User’s Manual, for a deﬁnition of the numbe ring of degrees of freedom

in ABAQUS/Standard. If this ﬁeld is left blank, all degrees of freedom will be constrained.
