Optimization of Steering Performance of All-terrain Vehicle in Terms of Turning Radius by Using Taguchi Method and Regression Approach

The transient response becomes the requirement of the vehicle when it comes to sharp cornering. The driving simulators are widely used by automotive manufactures. The smaller turning radius enable the vehicle to move within the available track by taking sharp turns. In the present study, the statistical approach is used for analyzing the steering behavior of the all-terrain vehicle. The vehicle dynamics was used to see the effects of the input parameters like camber, kingpin inclination angle, toe, wheelbase etc. affecting on turning radius of the all-terrain vehicle. As the turning radius is only the output thus Taguchi's orthogonal array was utilized to find the best optimum level of the process parameters so that they are least affected by noise factors for obtaining a robust design of parameters. The experiment was carried out using L36 orthogonal array. Analysis of variance was conducted to see the model adequacy and its significance.
