Overview
This section provides a reference to the spring elements available in Abaqus/Standard and Abaqus/Explicit.
Element types
| SPRINGA | Axial spring between two nodes, whose line of action is the line joining the two nodes. This line of action may rotate in large-displacement analysis. |
| SPRING1(S) | Spring between a node and ground, acting in a fixed direction |
| SPRING2(S) | Spring between two nodes, acting in a fixed direction |
Active degrees of freedom
SPRINGA: 1, 2, 3. The translational degree of freedom in the 3-direction is not activated in an Abaqus/Standard analysis if both nodes of the element are connected to two-dimensional entities such as two-dimensional analytical rigid surfaces, two-dimensional beam elements, etc.
SPRING1 or SPRING2: 1, 2, 3, 4, 5, or 6. If you specify a local orientation for the spring, these are local degrees of freedom. Otherwise, these are global degrees of freedom.
Nodal coordinates required
SPRINGA: X, Y, Z. These coordinates are used in the calculation of the action of the element.
SPRING1 or SPRING2: None. The element nodes do not need to have coordinates defined since the action associated with these elements is defined by specifying the degrees of freedom involved.
