Equivalent dynamic bearing load
public
Equivalent bearing load as a result of radial and axial bearing loads
Input
Radial load factor
$ X = 1 \; \; $
Radial load
$ F_r = 1 \; \; kN $
Axial load factor
$ Y = 1 \; \; $
Axial load
$ F_a = 1 \; \; kN $
Result
Equivalent dynamic load
$$ P_{dyn} = {X \cdot F_r + Y \cdot F_a} \; \; , {kN} $$
