Wheel Diameter of Vehicle Solution

STEP 0: Pre-Calculation Summary

Formula Used

Wheel Diameter of Vehicle = Rim Diameter+2*Tire Side Wall Height
d_w = D+2*H
This formula uses 3 Variables

Variables Used

Wheel Diameter of Vehicle - (Measured in Meter) - Wheel Diameter of Vehicle is defined as the total diameter of the wheel including the tire and rim diameter combined.
Rim Diameter - (Measured in Meter) - Rim Diameter is defined as the diameter of the circular profile of the rim on which the rubber tire is fitted on.
Tire Side Wall Height - (Measured in Meter) - Tire Side Wall Height is defined as the vertical length of the tire when measured from the top layer of tire to the rim layer.

STEP 1: Convert Input(s) to Base Unit

Rim Diameter: 0.434 Meter --> 0.434 Meter No Conversion Required
Tire Side Wall Height: 0.123 Meter --> 0.123 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d_w = D+2*H --> 0.434+2*0.123

Evaluating ... ...

d_w = 0.68

STEP 3: Convert Result to Output's Unit

0.68 Meter --> No Conversion Required

FINAL ANSWER

0.68 Meter <-- Wheel Diameter of Vehicle

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 Diameter of Vehicle Formula

Wheel Diameter of Vehicle = Rim Diameter+2*Tire Side Wall Height
d_w = D+2*H

What is wheel diameter of vehicle?

The wheel diameter dw [mm] is the sum between the rim diameter and twice the height of the tire. It is the combination of the rim's diameter and tire side wall height and it adds on to constitute the wheel's diameter as the rim and tire together form the wheel.
