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
