Connections
Connections are used to define the association of different regions of interest between parts in an assembly.
- Regular Connections
  Regular connections can be used to define contact-based connections between parts in an assembly.
- Precise Connections
  SimSolid creates precise connections on the fly during geometry import and are grouped under the Precise connection folder.
- Welds
  Welding is a process that joins materials, usually metals by using heat or pressure.
- Adhesives
  Structural adhesives are simulated as thin layers of adhesive material associated with a connection.
- Virtual Connector
  Virtual connectors are rigid imaginary parts created between selected faces/spots representing geometrical support of the connector.
  - Pin
    Connect an arbitrary number of coaxial cylindrical faces.
  - General Connector
    Create a rigid imaginary rigid part between arbitrary faces/spots.
  - Remote Support
    Connect faces or spots to a ground support.
  - Bushing
    Define directional stiffness and inertia coefficients.
  - Imported Bushing
    Defines directional stiffness between two parts that lie within specified diameter from the bushing center via importing a .csv file.
  - Rivet
    Connect multiple part with rivets of a given diameter.
  - Remote Mass
    Connect faces/spots of a single part to a remote mass represented as mass and moments of inertia.
  - Joints
    Connect faces/spots that can have relative motion in the form of displacements and/or rotations.
  - Cable/Rod
    Create a virtual cable/rod with finite or infinite stiffness between two different parts or between a single part and ground. Virtual cable/rod is applied on spots.

Bushing

Define directional stiffness and inertia coefficients.

A bushing is a type of vibration isolator that allows only a certain amount of movement. Bushings in SimSolid can be defined between two parts or between a single part and the ground. They are defined using directional stiffness and inertia. SimSolid supports zero, finite, and rigid stiffness.

Note: SimSolid does not support damping.

All bushing properties are defined with respect to a bushing reference coordinate system. X,Y axis of the reference coordinate system are defined using unit vectors.

Virtual connectors create perfectly rigid boundaries, stresses along the boundary faces can have local concentrations.

On the Project Tree, click on the Connections workbench
On the Connections workbench, click > Bushing > Bushing.
In the Virtual connector dialog, select an option for Bushing type.
Under Apply to, choose apply to Face or Spot.
In the modeling window, select parts on the model.
Optional: If applying to Spots, create new spots by clicking Create new spot.
Define the coordinate axis of the bushing.
1. Go to the Coordinate system tab.
2. The origin is set in COG by default. To edit the coordinates, uncheck the Set in COG checkbox and specify values for the X, Y, and Z fields.
3. Select an option for Axis.
4. Enter values for the X, Y, and Z direction.
Specify stiffness.
1. Go to the Stiffness tab.
2. Enter values for Linear X, Y, and Z.
3. Enter values for Angular X, Y, and Z.
Specify inertia.
1. Go to the Inertia tab.
2. Specify a value for Mass.
3. Under Inertia moments, specify values for X, Y, and Z.
Specify damping.
1. Go to the Damping tab.
2. Enter values for Translational and Rotational damping.
Click OK.
The virtual connector appears in the Connections branch. If selected, vectors representing the connection in the modeling window are displayed.
Note: Bushing with damping is only supported for complex eigen value analysis. Running modes automatically run complex modes.
