Front Bump Allowance given Front Ride Rate Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Constants Used

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

Variables Used

Front Bump Allowance - (Measured in Meter) - Front Bump Allowance is the vertical movement of the spring when the vehicle encounters a full bump.
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 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 Outside Wheel Change: 226 Kilogram --> 226 Kilogram 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

x₁ = (ΔW_fo*[g])/K_rf --> (226*[g])/31661

Evaluating ... ...

x₁ = 0.0700010391333186

STEP 3: Convert Result to Output's Unit

0.0700010391333186 Meter --> No Conversion Required

FINAL ANSWER

0.0700010391333186 ≈ 0.070001 Meter <-- Front Bump Allowance

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.
