## Wheel rate in vehicle Solution

STEP 0: Pre-Calculation Summary
Formula Used
Wheel rate of vehicle = Stiffness of Spring*((Motion ratio in suspension)^2)*(Spring angle correction factor)
Kt = k*((M.R.)^2)*(cosθ)
This formula uses 4 Variables
Variables Used
Wheel rate of vehicle - (Measured in Newton per Meter) - Wheel rate of vehicle is effectively the spring rate when measured at the wheel as opposed to at the spring.
Stiffness of Spring - (Measured in Newton per Meter) - Stiffness of Spring is a measure of the resistance offered by an elastic body to deformation. every object in this universe has some stiffness.
Motion ratio in suspension - Motion ratio in suspension is ratio of shock travel to the corresponding wheel travel.
Spring angle correction factor - Spring angle correction factor is cosine of the angle of the spring/shock absorber with vertical when viewed from front view of car.
STEP 1: Convert Input(s) to Base Unit
Stiffness of Spring: 0.75 Newton per Meter --> 0.75 Newton per Meter No Conversion Required
Motion ratio in suspension: 0.85 --> No Conversion Required
Spring angle correction factor: 0.95 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Kt = k*((M.R.)^2)*(cosθ) --> 0.75*((0.85)^2)*(0.95)
Evaluating ... ...
Kt = 0.51478125
STEP 3: Convert Result to Output's Unit
0.51478125 Newton per Meter --> No Conversion Required
0.51478125 0.514781 Newton per Meter <-- Wheel rate of vehicle

## All about Wheel rate of vehicle

Wheel rate is effectively the spring rate when measured at the wheel as opposed to at the spring. It is important to understand the wheel rate of a vehicle for calculating the spring rates and understanding the car dynamically. Wheel Rate is the effective spring rate at the wheel, due to the leverage advantage the wheel has with respect to the spring on the control arm.
