Section 16 Rigid Connections
SimLab – Rigid Connections (Application |Analysis | Structural | Connections) In SimLab, Structural Connections can be defined using any one of the tools. • RBAR • RBE • BAR • Spring • Bush • MPC • Joint • Gap Element • Plot Element • Spring Damper (For Ansys)
RBAR(Applications | Analysis | Structural | Connections | RBAR) • This tool is used to create Rigid Bar elements for Nastran or Beam MPC for Abaqus. • These elements can be created in many ways - between faces, edges, nodes.
RBE(Applications | Analysis | Structural | Connections | RBE) This tool is used to create Rigid Bar Elements for Nastran or Connector Elements for Abaqus. Create RBE by selecting Body / Face / Edge. Automatic center node creation based on centroid of selected entities.
Manual RBE(Applications | Analysis | Structural | Connections | Manual RBE) • This tool allows to create RBE elements by picking dependent and independent nodes manually. • First pick the independent node and then pick dependent nodes
This tool is used to create bar element between two nodes. Bar or Beam property has to be assigned. Bar(Applications | Analysis | Structural | Connections | BAR) Bar element between RBEs
Spring Elements can be created either by using Applications | Analysis | Structural | Connections | Spring (or) Applications | Analysis | Structural | Connections | Isotropic Spring 1.Spring This tool is used to create spring element between two nodes with each node having different degree of freedom. Springs(Applications | Analysis | Structural | Connections)
Springs 2.Isotropic Spring • This tool is used to create spring element between two nodes with each node having same degree of freedom. • Also spring elements along six degree of freedom with different stiffness can be created between two nodes.
Bush(Applications | Analysis | Structural | Connections | Bush) This tool is used to create Spring and Damper structural element for Nastran.
MPC(Applications | Analysis | Structural | Connections | MPC) This tool is used to define linear constraint equation between nodes. Constraint equations can be defined by selecting Dependent and Independent Faces / Edges / Nodes. Cyclic Symmetry boundary condition for Nastran can be specified.
MPC Dependent Face Independent Face
This tool is used to join two bodies using RBE2 or RBE3. Joint(Applications | Analysis | Structural | Connections | Joint)
This tool is used to create Gap Elements for Nastran. Gap Elements can be created between edges / faces. Matching nodes between edges / faces will be found out. Gap Elements(Applications | Analysis | Structural | Connections | GapElem)
This tool is used to create Plot Elements for Nastran. Plot Elements can be created between edges / faces. Matching nodes between edges / faces will be found out. Plot Elements(Applications | Analysis | Structural | Connections | PlotElem)
Spring Damper (For Ansys)(Applications | Analysis | Structural | Connections | Spring Damper) • This tool is used to define Spring Damper. It is specific for Ansys.
