Moving Boundary Manager, Translational

Moving Boundary Manager, Translational calculates normalized contact area ratio between two cuboid nodes or shapes with 1-D translational positions.

  

Description

The Moving Boundary Manager, Translational component is used for calculating normalized contact area ratio between two Cuboid or Cuboid Shape components.

This component can take account of 1-D translational positions connected with 1-D translational flange.

flange_a and flange_b are the center position of each Cuboid or Cuboid Shape.

The order of coefficients of normalized contact area ratio Ac_a and Ac_b output from Real Signal output ports is as follows.

a1−b1, ... ,a1−bm,a2−b1, ... ,a2−bm, ...... ,an−b1, ... ,an−bm

For example, when Nodes_a = 2 and Nodes_b =3,  then  Ac_b4 means a2−b1,the coefficient of normalized area ratio of flange_b side between Nodes_ a2− Nodes_ b1.

 

The geometry parameters are the following.

 

The contact width W__contact is defined as follows.

Equations

The coefficients of normalized contact area ratio are defined as follows.

 Ac_ai=Ai, jA_a   0 ≤ Ac_ai≤1 Ac_bj=Ai, jA_b    0 ≤Ac_bj≤1 nc_Ac_ai = 1−∑Ac_ak  k=ai−b1, ai−b2,..., ai−bNodes_b

nc_Ac_bj = 1−∑Ac_bk k=a1−bj, a2−bj,..., aNodes_a−bj
