Vertical motion

Coefficients of vertical motion:

$\eta \left(t\right)={\eta }_6{t}^6+{\eta }_5{t}^5+{\eta }_4{t}^4+{\eta }_3{t}^3+{\eta }_2{t}^2+{\eta }_{1}t+\eta$

The profile of additional motion in generating processes is described by a polynomial in t of degree n ≤ 6. The variable t corresponds to the cradle angle t = (α-α_m), where α_m is the center roll position.

The aim of these additional motions is to generate flank modifications.
