CAD Study
Steering gear determines the amount of torque
required on wheel depend on hand wheel torque
Tolerance between new gear and gear which has
determines whether the component needs to be
replaced or not
Different types of steering gear are used depend on
vehicle
CAD has intelligence to detect gear parameters
under all conditions
CAD tool to detects the list of all critical components
which affect vehicle performance

CAD Measured Parameters
Steering torque, Steering wheel torque
Steering angle
Engine speed
Load
MATLAB application:-
It contains correlation data obtained from all
possible combination for the particular steering gear
Correlation data basically a matrix obtained from
pattern recognition techniques
