Calculate Unsprung Weight







Formula

The formula to calculate the unsprung weight is:

\[ \text{UW} = \text{WW} + \text{TW} + \text{BW} + \text{SW} \]

What is Unsprung Weight?

Unsprung weight refers to the mass of the vehicle that is not supported by the suspension system. This includes components such as the wheels, tires, brakes, and parts of the suspension itself. Unsprung weight affects the vehicle’s handling and ride quality, as it can influence the suspension’s ability to isolate the vehicle’s body from road irregularities. Reducing unsprung weight can lead to improved handling and faster suspension response.

Example Calculation

Let's assume the following values:

Using the formula:

\[ \text{UW} = 50 + 40 + 30 + 20 = 140 \, \text{lbs} \]

The unsprung weight (UW) is 140 lbs.
