Equivalent Dynamic Load Calculator

Formula

The formula to calculate the Equivalent Dynamic Load (P) is:

$P = X \cdot Fr + Y \cdot Fa$

Where:

P – The equivalent dynamic load in kilonewtons (kN).
X – The radial load factor.
Fr – The radial bearing load in kilonewtons (kN).
Y – The axial load factor.
Fa – The axial bearing load in kilonewtons (kN).

Definition

Equivalent Dynamic Load (P): The combined effect of the static load and the centrifugal force in a bearing.
Radial Load Factor (X): A factor that accounts for the radial load on the bearing.
Radial Bearing Load (Fr): The load acting radially on the bearing.
Axial Load Factor (Y): A factor that accounts for the axial load on the bearing.
Axial Bearing Load (Fa): The load acting axially on the bearing.

Example

Let's say the radial load factor (X) is 0.56, the radial bearing load (Fr) is 5 kN, the axial load factor (Y) is 1.2, and the axial bearing load (Fa) is 3 kN. Using the formula:

$P = 0.56 \cdot 5 + 1.2 \cdot 3 = 2.8 + 3.6 = 6.4 \text{ kN}$

So, the equivalent dynamic load is 6.4 kN.
