Rear Ride Rate Solution

STEP 0: Pre-Calculation Summary

Formula Used

Rear Ride Rate = (Rear Outside Wheel Change*[g])/Rear Bump Allowance
K_r = (ΔW_ro*[g])/x₂
This formula uses 1 Constants, 3 Variables

Constants Used

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

Variables Used

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

STEP 1: Convert Input(s) to Base Unit

Rear Outside Wheel Change: 161.87 Kilogram --> 161.87 Kilogram No Conversion Required
Rear Bump Allowance: 0.05 Meter --> 0.05 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

K_r = (ΔW_ro*[g])/x₂ --> (161.87*[g])/0.05

Evaluating ... ...

K_r = 31748.04871

STEP 3: Convert Result to Output's Unit

31748.04871 Newton per Meter --> No Conversion Required

FINAL ANSWER

31748.04871 ≈ 31748.05 Newton per Meter <-- Rear Ride Rate

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.
