Creating Flexible Supports 

This task shows you how to create flexible supports.
A flexible support represents the assembly on tooling. It is represented by a series of points and a beam between two consecutive points. Different mechanical rigidities can be defined for each beams.
Selecting one point is equivalent to creating a rigid support.
It is not possible to re-use a point already used as support (rigid or flexible). 
These points can be:
 
  • Several or all the V5 Points from one or several V5 Open Body.
  • Several V4 mesh nodes from one or several V4 meshes.
A flexible support can move during the assembly and the analysis.
The flexible support is stored in a CATPart document of the resource list.
Open the BasicTaaProcess2.CATProcess document.

  1. Click Flexible Support .

  1. Select the TasResources product resource from which the support will be created.

    The Flexible Support Definition dialog box appears.
    Three types of flexible supports may be defined:
 
 
User define
For each beam, you must define:
  • Kx: compression stiffness along x axis of the beam.
  • Ky: flexion stiffness along y axis of the beam.
  • Kz: flexion stiffness along z axis of the beam.
  • Kt: torsion stiffness around x axis of the beam
  • DZx: normal direction of the beam along x axis of the part.
  • DZy: normal direction of the beam along y axis of the part.
  • DZz: normal direction of the beam along z axis of the part.
Circular
For each beam, you must define:
  • Radius: radius of the beam.
  • Young Module
  • Poisson Coefficient
Rectangular
For each beam, you must define:
  • Base: rectangular base of the beam.
  • Height: rectangular height of the beam.
  • DZx: normal direction of the beam along x axis of the part.
  • DZy: normal direction of the beam along y axis of the part.
  • DZz: normal direction of the beam along z axis of the part.
  • Young Module
  • Poisson Coefficient
 

  1. Select the Circular type.

  1. Select the Support Points 2 open body.

  2. Select each radius field and specified 5mm.

  3. Specify 2.1e+006 as Young module.

  4. Click OK.

    The Flexible Support.1 is created according to the selected points.
