Fields
Use the Fields tool to create a compliant connection between two bodies where stiffness or damping in one direction can be a function of displacement in another direction
Create Fields
Edit Fields
Define the Connectivity of Fields
The Connectivity tab allows you to define the bodies and orientation used by the compliant connection.
Define the Stiffness of Fields
The Stiffness tab allows you to enter stiffness values into a 6x6 matrix. The stiffness values along the diagonal of the matrix represent stiffness in the direction of displacement, whereas the other values represent cross-coupling stiffness.
- Click to define an MDL expression for any one of the values.
- If the field is a pair entity, click Symmetric stiffness to make the stiffness values symmetric. Once this option is activated, MotionView will ask you which side of the values of the pair entity (left or right) is to be used. Selecting any one side will make values of that side as “leader” and the values of the other side ("follower") will gray out and follow the values on the leader side.
Define the Damping of Fields
The Damping tab allows you to enter damping values into a 6x6 matrix. The damping values along the diagonal of the matrix represent stiffness in the direction of velocity, whereas the other values represent cross-coupling damping.
Define the Preload and Freelength of Fields
The Preload/Freelength tab allows you to provide initial forces or free lengths along the six primary directions of the field connection.
Use User-Defined Properties for a Field
If desired, define the field using the User-Defined tab, which will allow you to specify the properties of the field using user subroutines.
