Create Cable
This icon launches the Create Cable wizard from which the following combination of
Anchor Creation,
Pulley Creation and
Cable Wrapping can be created:
Anchor Creation
Anchors are needed to define the begin and end of an open cable.
■Without anchors, cable wrapping creates a closed cable.
■With anchors, cable wrapping creates an open cable.
Pulley Creation
Pulley specification is divided into two main sub components: the pulley property set which specifies the cross-sectional and material properties of the pulley and the pulleys themselves which refer to a given pulley property set and additionally specify the location and diameter of the pulley.
Cable Wrapping
Cable Wrapping is performed from the Cable System wizard by selecting the order through which the cable will be routed within the pulleys. It should be noted that other parameters besides the pulley and anchor locations can influence the cable wrapping and therefore when modified will force a re-wrapping of the cable; these parameters include:
■Anchor:
■Location of anchor
■Pulley:
■Location
■Angular Mis-alignment (X)
■Angular Mis-alignment (Y)
■Diameter
■Properties
■Pulley properties:
■Depth
■Hertz_K (stiffness)
■Hertz_E (exponent)
■Cable properties:
■Begin, track and end (that is, ordered list of routing elements)
■Diameter
■Preload
■Formulation:
♦Simplified: gravity, inertia, disengagement
♦Discretized: mesh, zone, delta
■Pulley_results, Span_results
If, outside of the wizard, one modifies the position of a pulley's or anchor's reference marker, a dependency notification is provided that the cable will need to be re-wrapped. Similarly, if any modifications are made manually (that is, outside of the Cable System wizard) which necessitate the re-wrapping of the cable a dependency notification is provided that the cable will need to be re-wrapped.
