You can use the cable connector to simulate cables, ropes, or chains in
an assembly, which act either as supporting members or perform load lifting
operations.
You can define the cable connector between solid surfaces, shell edges, or
vertices (of solids or shells), or a combination of vertices to faces, vertices to
circular edges, and circular edges to faces.
Cable connectors are tension-only elements that carry axial forces when
subjected to tensile loading. The cable connector only becomes active when the distance
between the two ends exceeds its initial or pretensioned length, at which point the
cable develops tensile stresses and helps in supporting the structure.
The cable connector uses the distributed coupling formulation to connect a
reference node, which is located at the end joints of the cable, to a group of coupling
nodes of the selected face or edge. If you select a vertex, the cable is connected to a
group of surrounding nodes within the area of influence. Distributing coupling
constrains the motion of the coupling nodes to the translational motion of the reference
node.
After running a simulation with cable connectors, you can list the
connectors' forces, such as axial force and torque. Shear force and bending moment are
not valid results, as the cable is designed for tension and does not have bending
stiffness. Results are reported with respect to the cable's local coordinate system,
which is defined from the first reference node to the second, based on the order of
selection. The axial force might show a positive or negative value, depending on its
direction relative to the connector's local axis. If a cable experiences compressive
loads, the cable becomes slack and reports the axial force as zero.
Cable connector force results are color-coded based on the reported
forces and the defined safe axial strength. This helps you quickly evaluate if the cable
connector is overstressed, within safe limits, or inactive because it is under
compression.
Color |
Description |
Green (within safe limits) |
The reported cable axial force is within the
specified safe axial strength. |
Red (overstressed) |
The reported cable axial force exceeds the
specified safe axial strength. |
Yellow (inactive) |
The reported cable axial force is zero (cable is
slack or under compression). |
The cable connector is supported for linear static studies and is
available with SOLIDWORKS Simulation Professional and SOLIDWORKS Simulation Premium.
