Moving Boundary Manager, Rotational
Moving Boundary Manager, Rotational calculates normalized contact area ratio between concentric cylindrical / ring sector and shape with 1-D rotational angles.
Description
The Moving Boundary Manager, Rotational component is used for calculating normalized contact area ratio between two concentric Cylindrical / Ring Sector and Cylindrical / Ring Shape B components.
This component can take account of 1-D rotational angles connected with 1-D rotational flange.
flange_a is the rotational angle of center of Sector. flange_b is the rotational angle of center of Node[1] in Cylindrical / Ring Shape B.
The order of coefficients of normalized contact area ratio Ac_a and Ac_b output from Real Signal output ports is as follows.
a−b1, ... ,a−bn
The geometry parameters are the following.
Equations
The coefficients of normalized contact area ratio are defined as follows.
Ac_ai=AiA_a 0 ≤ Ac_ai≤1 Ac_bi=AiA_b 0 ≤Ac_bi≤1 nc_Ac_a = 1−∑Ac_ak k=1,..., Nodes_b nc_Ac_bi = 1−Ac_bi
