Tractive Effort in Multi-Geared Vehicle at any given Gear
Go Tractive Effort in Multi-geared Vehicle = (Torque Output of Vehicle*Gear Ratio of Transmission*Gear Ratio of Final Drive*Transmission Efficiency of Vehicle)/Effective Radius of Wheel
Normal Load on Wheels due to Gradient
Go Normal Load on Wheels due to Gradient = Vehicle Weight in Newtons*Acceleration due to Gravity*cos(Angle of Inclination of Ground from Horizontal)
Wheel Force
Go Wheel Force = 2*Engine Torque*Transmission Efficiency of Vehicle/Diameter of Wheel*Engine Speed in rpm/Wheel Speed
Curb Force for Driven Wheel
Go Curb Force for Driven Wheel = (Weight on Single Wheel*Contact Point Distance from Wheel Center Axis)/(Effective Radius of Wheel-Height of Curb)
Slip of Tire
Go Slip of Tire = ((Forward Velocity of Vehicle-Vehicle Wheel Angular Velocity*Effective Radius of Wheel)/Forward Velocity of Vehicle)*100
Gradient Resistance of Vehicle
Go Gradient Resistance = Vehicle Weight in Newtons*Acceleration due to Gravity*sin(Angle of Inclination of Ground from Horizontal)
Longitudinal Slip Velocity
Go Longitudinal Slip Velocity = Axle Speed over Roadway*cos(Slip Angle)-Circumferential Velocity of Tire under Traction
Contact Point of Wheel and Curb Distance from Wheel Center Axis
Go Contact Point Distance from Wheel Center Axis = sqrt(2*Effective Radius of Wheel*(Height of Curb-Height of Curb^2))
Traction Force Required to Climb Curb
Go Traction Force required to Climb Curb = Weight on Single Wheel*cos(Angle between Traction Force and Horizontal Axis)
Angle between Traction Force and Horizontal Axis
Go Angle between Traction Force and Horizontal Axis = asin(1-Curb Height/Effective Radius of Wheel)
Longitudinal Slip Velocity for Zero Slip Angle
Go Longitudinal (Angular) Slip Velocity = Angular Velocity of Driven (or braked) Wheel-Angular Velocity of Free Rolling Wheel
Lateral Slip Velocity
Go Lateral Slip Velocity = Axle Speed over Roadway*sin(Slip Angle)
Mechanical Advantage of Wheel and Axle
Go Mechanical Advantage of Wheel and Axle = Effective Radius of Wheel/Radius of Axle
Wheel Diameter of Vehicle
Go Wheel Diameter of Vehicle = Rim Diameter+2*Tire Side Wall Height
Tire Side Wall Height
Go Tire Side Wall Height = (Aspect Ratio of Tire*Tire Width)/100
Aspect Ratio of Tire
Go Aspect Ratio of Tire = Tire Side Wall Height/Tire Width*100
Variation of Rolling Resistance Coefficient at Varying Speed
Go Rolling Resistance Coefficient = 0.01*(1+Vehicle Speed/100)
Circumference of Wheel
Go Wheel Circumference = 3.1415*Wheel Diameter of Vehicle
Wheel Radius of Vehicle
Go Wheel Radius in Meter = Wheel Diameter of Vehicle/2

Wheel Radius of Vehicle Formula

Wheel Radius in Meter = Wheel Diameter of Vehicle/2
rw = dw/2

What is the radius of wheel mean?

The (free static) wheel radius rw [mm] is half the wheel diameter. To take into account the deformation of the tire, we can apply a coefficient of 0.95, which means that the free static radius will decrease with approx. 5% under load (vehicle weight).

How to Calculate Wheel Radius of Vehicle?

Wheel Radius of Vehicle calculator uses Wheel Radius in Meter = Wheel Diameter of Vehicle/2 to calculate the Wheel Radius in Meter, The Wheel radius of vehicle formula is defined as the radius of the wheel of a vehicle and is half the wheel diameter. Wheel Radius in Meter is denoted by rw symbol.
