This special event will walk through a completed model, showing how it was constructed, including the inputs and outputs.
The outputs include comparing the rigid kinematic model to the compliant kinematic model, an analysis of the bump steer impact from variation, and wheel alignment changes (camber, caster, toe).
Wheel alignment values which are measured on the aligner are considered in this model for measurements.
Mainly Camber, caster, Toe also Ride Height. And using Kinematic motion bump steer slope is plotted, which is the effect of Toe change through out the range of motion.
Bump Steer -
Bump steer is a change in the steering angle of the wheel when the wheel is in bump or droop without turning of the steering wheel. Bump steer is highly undesirable within racing especially on tracks or surfaces that contain bumps. If the suspension is constantly transitioning between bump and droop, then a car with bump steer will constantly be shifting the steering angle of the car and will make the front end very unstable at high speeds.
King Pin or Steering Axis Angle –
View from front. Angle between line joining ball joint centers of control arms and reference vertical plane/line.
