Wheel Rate Calculator

Formula

The formula to calculate the Wheel Rate (WR) is:

\[ WR = K \times M^2 \]

Where:

Wheel Rate (WR): The effective spring rate at the wheel, measured in pounds-force per inch (lbf/in).
Spring Constant (K): The stiffness of the spring, measured in pounds-force per inch (lbf/in).
Motion Ratio (M): The ratio of the wheel's movement to the spring's movement, a dimensionless quantity.

Let's say the spring constant (K) is 300 lbf/in and the motion ratio (M) is 0.8. Using the formula:

\[ WR = 300 \times 0.8^2 \]

We get:

\[ WR = 192 \, \text{lbf/in} \]

So, the wheel rate is 192 lbf/in.
