You can create kinematics
contacts between bodies of a mechanism by selecting the bodies that come into contact,
adjusting their mesh, and specifying the contact properties.
Before you begin:
Create a mechanism.
Create bodies with a geometry assigned.
From the Assembly section of the action bar,
click 3D Contact.
In the Define Contact section, select one of the following
options to determine which bodies are coming into contact:
Option
Description
Within one list
Lists the bodies from the mechanism that come into contact.
Note:
Use this
option if all bodies from the mechanism are coming into contact or if you are
uncertain which bodies are to come into contact.
Between two lists
Lists two groups of bodies that come into contact with one another.
Note:
Use
this option if you know which bodies are to come into contact.
Note:
All the volume geometries of the selected bodies are used for contact.
Depending on your selection, one or two contact lists appear.
If you click Within one list, select at least two bodies from
the current mechanism.
Each body is paired with the other bodies from the list.
The Number of contact pairs is computed automatically.
Note:
The computed number equals the number of possible combinations between bodies
from the Contact list.
If you click Between two lists, in the Contact list
1 and Contact list 2, select one or more bodies from
the current mechanism.
Every body from Contact list 1 is paired with every body from
Contact list 2.
Note:
Bodies from the same list are not
paired with one another.
The Number of contact pairs is computed automatically.
Note:
The computed number equals the number of contact pairs between every body from
Contact list 1 and every body from Contact list
2.
In the Mesh section, specify the mesh density of the contacting
surfaces. To do so:
Enter a value in the Mesh densityfield.
Move the slider to adjust the mesh density of the contacting surfaces.
The default value for the mesh density is 35. You can specify a value between 0
(coarse mesh) and 100 (fine mesh).
