λ = ((v-ω*rd)/v)*100
This formula uses 4 Variables
Variables Used
Slip of Tire - Slip of Tire is defined as the relative motion between a tire and the road surface it is moving on.
Forward Velocity of Vehicle - (Measured in Meter per Second) - Forward Velocity of Vehicle is defined as the velocity of the vehicle moving in forward direction at any instant.
Vehicle Wheel Angular Velocity - (Measured in Radian per Second) - Vehicle Wheel Angular Velocity is defined as the wheel that is in motion on a road rotates with a velocity called angular velocity.
Effective Radius of Wheel - (Measured in Meter) - The Effective radius of Wheel is the radius of the part of the wheel which remains undeformed while rolling.
STEP 1: Convert Input(s) to Base Unit
Forward Velocity of Vehicle: 50 Meter per Second --> 50 Meter per Second No Conversion Required
Vehicle Wheel Angular Velocity: 12 Radian per Second --> 12 Radian per Second No Conversion Required

λ = ((v-ω*rd)/v)*100

What is slip of tire?

Slip is the relative motion between a tire and the road surface it is moving on. This slip can be generated either by the tire's rotational speed being greater or less than the free-rolling speed (usually described as percent slip), or by the tire's plane of rotation being at an angle to its direction of motion.

How to Calculate Slip of Tire?

Slip of Tire calculator uses Slip of Tire = ((Forward Velocity of Vehicle-Vehicle Wheel Angular Velocity*Effective Radius of Wheel)/Forward Velocity of Vehicle)*100 to calculate the Slip of Tire, The Slip of tire formula is defined as a percentage of the difference between the surface speed of the wheel compared to the speed between axle and road surface. Slip of Tire is denoted by λ symbol.

How to calculate Slip of Tire using this online calculator? To use this online calculator for Slip of Tire, enter Forward Velocity of Vehicle (v), Vehicle Wheel Angular Velocity (ω) & Effective Radius of Wheel (rd) and hit the calculate button. Here is how the Slip of Tire calculation can be explained with given input values -> 86.8 = ((50-12*0.55)/50)*100.
