InternalSupport

Adapter model to utilize conditional support connector

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This is an adapter model to utilize a conditional support connector in a component. It could be applied to both textually (equations based) and graphically defined components:

  • If useSupport = true, this flange has to be connected to the conditional support connector.
  • If useSupport = false, this flange has to be connected to the conditional fixed model.

Variable f is defined as input. It must be provided as a modifier and computed via a force balance when using this model in textually defined components. This approach of internal support is utilized, e.g., via the following partial models:

Note, the support position can always be accessed as internalSupport.s, and the support force can always be accessed as internalSupport.f.

Inputs (1)

f

Type: Force (N)

Description: External support force (must be computed via force balance in model where InternalSupport is used; = flange.f)

Connectors (1)

flange

Type: Flange_a

Description: Internal support flange (must be connected to the conditional support connector for useSupport=true and to conditional fixed model for useSupport=false)
