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
