Steer Angle given Understeer Gradient Solution

STEP 0: Pre-Calculation Summary

Formula Used

Steer Angle = (57.3*(Wheelbase of Vehicle/Radius of Turn))+(Understeer Gradient*Horizontal Lateral Acceleration)
δ = (57.3*(L/R))+(K*A_α)
This formula uses 5 Variables

Variables Used

Steer Angle - (Measured in Radian) - Steer Angle is the angle between the vertical axis of a vehicle's steering system and the direction of the wheels.
Wheelbase of Vehicle - (Measured in Meter) - Wheelbase of Vehicle is the distance between the center of the front and rear wheels, affecting the vehicle's stability and steering performance.
Radius of Turn - (Measured in Meter) - Radius of Turn is the distance from the center of rotation to the center of the vehicle's rear axle during a turn in a steering system.
Understeer Gradient - (Measured in Radian) - Understeer Gradient is a measure of a vehicle's tendency to turn less than intended, resulting in a wider turn radius, particularly during high-speed cornering.
Horizontal Lateral Acceleration - (Measured in Meter per Square Second) - Horizontal Lateral Acceleration is the acceleration of an object as it moves horizontally and laterally, particularly in the context of vehicle steering and handling dynamics.

STEP 1: Convert Input(s) to Base Unit

Wheelbase of Vehicle: 2700 Millimeter --> 2.7 Meter (Check conversion here)
Radius of Turn: 10000 Millimeter --> 10 Meter (Check conversion here)
Understeer Gradient: 0.218 Radian --> 0.218 Radian No Conversion Required
Horizontal Lateral Acceleration: 1.6 Meter per Square Second --> 1.6 Meter per Square Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

δ = (57.3*(L/R))+(K*A_α) --> (57.3*(2.7/10))+(0.218*1.6)

Evaluating ... ...

What is steer angle and what is its significance?

Steering angle means the angle between the projection of a longitudinal axis of the vehicle and the line of intersection of the wheel plane (being the central plane of the wheel, normal to the axis around which it rotates) and the road surface. At higher speeds, the lateral acceleration during cornering increases and it cannot be neglected. This gives rise to slip angles at the wheels and the tires produce lateral forces in order to counteract the lateral acceleration.
