Taking the elastic deformation of parts into account in calculations to simulate the characteristics of suspension alignment was confirmed to improve prediction accuracy. Taking the elastic deformation of the main elements of the overall suspension, the sub-frame, and the body into account made it possible to accurately determine the side force compliance at the tire contact point with the ground, and also to clarify the contribution made by each of those parts. Development of an elastic body modeling method that accounts for significant deformation made it possible to improve the accuracy of alignment prediction, even in parts such as the twist beam axle that undergo significant deformation. Software was developed to assist with design analysis so that these prediction methods could be utilized in practical design work.
