6.4.3.4. Sphere In Cylinder

A Sphere In Cylinder Contact generates a force between a sphere and a cylinder.

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

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

  • 1The sphere must be inside of the cylinder.

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

6.4.3.4.1. Modeling Options

In the case of Sphere In Cylinder contact, a sphere geometry type is supported for an action geometry and a cylinder geometry type is supported for a base geometry when creating.

  • Cylinder, Sphere

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

    • Sphere: Selects a sphere to define an action sphere.

  • Cylinder, MultiSphere

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

    • MultiSphere: Selects some spheres to define action spheres.

  • Cylinder, Sphere, Cylinder, Sphere

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

    • Sphere: Selects a sphere to define an action sphere.

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

    • Sphere: Selects a sphere to define another action sphere.

  • MultiCylinder, MultiSphere

    • MultiCylinder: Selects some cylinders to define base cylinders.

    • MultiSphere: Selects some spheres to define action spheres.

Figure 6.358 Properties of SphereInCylinder 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 Face is automatically shown on the Working Window.

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

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

  • Definition of The Action Sphere

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

    • Radius: Shows the radius of an action sphere.

  • Synchronize with Geometry

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

    • If this option is not checked, the user can modify the contact properties.

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