Calculate Motion Ratio (MR)



Formula

The formula to calculate the Motion Ratio (MR) is:

\[ MR = \frac{dS}{dW} \]

Where:

What is a Motion Ratio?

The Motion Ratio (MR) is a measure of the relationship between the movement of the shock absorber (dS) and the movement of the wheel (dW) in a suspension system. It is an important factor in the design and tuning of suspension systems in vehicles, particularly in performance and racing applications. A higher motion ratio means the shock moves more for a given wheel movement, which can affect the stiffness and response of the suspension.

Example Calculation

Let's consider an example:

Using the formula to calculate the Motion Ratio (MR):

\[ MR = \frac{2}{4} = 0.50 \]

This means that the motion ratio is 0.50, indicating that the shock moves half the distance of the wheel movement.
