Front Outside Wheel Load Change given Front Ride Rate Solution

STEP 0: Pre-Calculation Summary

Formula Used

Front Outside Wheel Change = (Front Bump Allowance*Front Ride Rate)/[g]
ΔW_FO = (x₁*K_RF)/[g]
This formula uses 1 Constants, 3 Variables

Constants Used

[g] - Gravitational acceleration on Earth Value Taken As 9.80665

Variables Used

Front Outside Wheel Change - (Measured in Kilogram) - Front outside wheel change is the difference between the load on the wheels during cornering and the load during straight path travel.
Front Bump Allowance - (Measured in Meter) - Front Bump Allowance is the vertical movement of the spring when the vehicle encounters a full bump.
Front Ride Rate - (Measured in Newton per Meter) - Front Ride Rate is defined as vertical force per unit vertical displacement of the tire ground contact with respect to chassis.

STEP 1: Convert Input(s) to Base Unit

Front Bump Allowance: 0.07 Meter --> 0.07 Meter No Conversion Required
Front Ride Rate: 31661 Newton per Meter --> 31661 Newton per Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ΔW_FO = (x₁*K_RF)/[g] --> (0.07*31661)/[g]

Evaluating ... ...

ΔW_FO = 225.996645133659

STEP 3: Convert Result to Output's Unit

225.996645133659 Kilogram --> No Conversion Required

FINAL ANSWER

225.996645133659 ≈ 225.9966 Kilogram <-- Front Outside Wheel Change

< 12 Ride Rate and Ride Frequency for Race Cars Calculators

Front Ride Frequency

Go Ride Frequency = 0.5/pi*sqrt(Front Ride Rate/Load on Individual Wheel in Static Condition)

Rear Ride Frequency

Go Ride Frequency = 0.5/pi*sqrt(Rear Ride Rate/Load on Individual Wheel in Static Condition)

Load on Front Wheel given Front Ride Frequency

Go Load on Individual Wheel in Static Condition = Front Ride Rate/((Ride Frequency*2*pi)^2)

Load on Rear Wheel given Rear Ride Frequency

Go Load on Individual Wheel in Static Condition = Rear Ride Rate/((Ride Frequency*2*pi)^2)

Front Ride Rate given Front Ride Frequency

Go Front Ride Rate = (Ride Frequency*2*pi)^2*Load on Individual Wheel in Static Condition

Rear Ride Rate given Rear Ride Frequency

Go Rear Ride Rate = (Ride Frequency*2*pi)^2*Load on Individual Wheel in Static Condition

Front Outside Wheel Load Change given Front Ride Rate

Go Front Outside Wheel Change = (Front Bump Allowance*Front Ride Rate)/[g]

Front Bump Allowance given Front Ride Rate

Go Front Bump Allowance = (Front Outside Wheel Change*[g])/Front Ride Rate

Front Ride Rate

Go Front Ride Rate = (Front Outside Wheel Change*[g])/Front Bump Allowance

Rear Outside Wheel Load Change given Rear Ride Rate

Go Rear Outside Wheel Change = (Rear Bump Allowance*Rear Ride Rate)/[g]

Rear Bump Allowance given Rear Ride Rate

Go Rear Bump Allowance = (Rear Outside Wheel Change*[g])/Rear Ride Rate

Rear Ride Rate

Go Rear Ride Rate = (Rear Outside Wheel Change*[g])/Rear Bump Allowance

Front Outside Wheel Load Change given Front Ride Rate Formula

Front Outside Wheel Change = (Front Bump Allowance*Front Ride Rate)/[g]
ΔW_FO = (x₁*K_RF)/[g]

Ride rates in a vehicle

Ride rate refers to the rate of change of tire normal force with vertical body movement and roll rate refers to the rate of change of tire normal force with body roll about its roll axis. The ride and roll rates of the car affect the wheel loading wrt the body position change and the wheel load or tire normal force determines the available tire lateral/longitudinal forces which directly impacts the vehicle performance. Individual suspension components like springs and antiroll bar affect the vehicle ride and roll. The ride performance of the car is many a times in conflict with the roll performance and hence choosing the correct springs and anti roll bar is often a balancing act.
