6.4.3.14. Cylinder In Cylinder

A Cylinder In Cylinder Contact generates a force between two cylinders.

  • The cylinder and cylinder must belong to two different bodies.

  • The cylinder must be defined an action geometry and the cylinder must be defined a base geometry.

  • The action cylinder must be inside of the base cylinder initially.

  • The contact force can be generated with not only linear or exponential but also nonlinear spline characteristics to the contact penetration and its velocity.

6.4.3.14.1. Modeling Options

In the case of Cylinder In Cylinder contact, a cylinder geometry type is supported without base and action geometries when creating.

  • Cylinder, Cylinder

    • Cylinder: Selects a cylinder to define a base cylinder.

    • Cylinder: Selects a cylinder to define an action cylinder.

  • Cylinder, MultiCylinder

    • Cylinder: Selects a cylinder to define a base cylinder.

    • MultiCylinder: Selects some cylinders to define action cylinders.

  • Cylinder, Cylinder, Cylinder, Cylinder

    • Cylinder: Selects a cylinder to define a base cylinder.

    • Cylinder: Selects a cylinder to define an action cylinder.

    • Cylinder: Selects a cylinder to define another base cylinder.

    • Cylinder: Selects a cylinder to define another action cylinder.

  • MultiCylinder, MultiCylinder

    • MultiCylinder: Selects some cylinders to define base cylinders.

    • MultiCylinder: Selects some cylinders to define action cylinders.

  • MultiCylinder

    • MultiCylinder: Selects some cylinders to define base and action cylinders each other.

Note

In case of MultiCylinder modeling, contacts are created correctly if selecting the order of the radius of the cylinders.

Figure 6.376 Properties of CylinderInCylinder dialog box

  • Definition of The Base Cylinder

    • Entity Name: Defines the name of base cylinder. The base cylinder can be dispatched from the Working Window by clicking Gr.

    • Radius: Shows the radius of base cylinder.

    • Length: Shows the length of base cylinder.

    • Open Face: The cylinder geometry has three faces. Two of the faces are in both end sides, and they are closed as default. If the user wants to open the side, the user can do it with using this option. The checked open faces are automatically shown on the Working Window.

      • Start Face is located in start point of the cylinder.

      • End Face is located in end point of the cylinder.

  • Definition of The Action Cylinder

    • Entity Name: Defines the name of action cylinder. The action cylinder can be dispatched from the Working Window by Gr.

    • Radius: Shows the radius of action cylinder.

    • Length: Shows the length of action cylinder.

  • Synchronize with Geometry

    • If this option is checked, Radius and Length in contact properties automatically defined with that of the specified graphics. (The default is checked.)

    • If the user unchecked this, the user can modify the contact properties.

  • Force Display: Graphically displays the resultant force vector on the view window.
