Motion Ratio or Installation Ratio in Suspension Solution

STEP 0: Pre-Calculation Summary

Formula Used

Motion Ratio in Suspension = Spring or Shock Travel/Wheel Travel
M.R. = ST/WT
This formula uses 3 Variables

Variables Used

Motion Ratio in Suspension - Motion Ratio in Suspension is the ratio of the angular displacement of the steering axis to the angular displacement of the wheel.
Spring or Shock Travel - (Measured in Meter) - Spring or Shock Travel Steering is the maximum distance that a spring or shock absorber in a steering system can compress or extend.
Wheel Travel - (Measured in Meter) - Wheel Travel is the maximum distance that the wheel of a vehicle can move up and down, measured from the highest to the lowest point.

STEP 1: Convert Input(s) to Base Unit

Spring or Shock Travel: 65 Millimeter --> 0.065 Meter (Check conversion here)
Wheel Travel: 100 Millimeter --> 0.1 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

M.R. = ST/WT --> 0.065/0.1

Evaluating ... ...

M.R. = 0.65

what is Motion or Installation ratio?

An installation ratio is the ratio between how much the spring and damper moves in relation to how far the wheel and tyre move. In general, the wheel and tyre will move a further distance than the spring and damper. The installation ratio is vital to understand in your suspension set up particularly if you are planning on choosing you own spring rates as it helps to determine the effective spring rate at the wheel known as “wheel rate”. It therefore determines the amount of deflection that the spring and damper and anti-roll bar will experience at any displacement of the wheel and tyre.

How to Calculate Motion Ratio or Installation Ratio in Suspension?

Motion Ratio or Installation Ratio in Suspension calculator uses Motion Ratio in Suspension = Spring or Shock Travel/Wheel Travel to calculate the Motion Ratio in Suspension, Motion Ratio or Installation Ratio in Suspension formula is defined as a dimensionless quantity that represents the ratio of the sprung mass to the unsprung mass of a vehicle's suspension system, providing a measure of the suspension's ability to absorb shocks and vibrations. Motion Ratio in Suspension is denoted by M.R. symbol.
