Estimation Of Friction Circle For Assessment Of Tyre Sliding Behavior Through FEA
Abstract- The friction force characteristics of a tyre help us in understanding its performance under braking and traction
condition. In the contact plane, this friction force determines the tyre lateral force and longitudinal force response. To
understand the variation of these two components of the forces is always an area of interest for the researchers. For this
purpose, tyre-force ellipse/circle (more frequently referred to as friction ellipse and friction circle respectively) models are
being used frequently. The tyre force circle/ellipse incorporates slip angle, traction slip and actual non linear tyre force. In this
paper, we estimated the tyre friction circle under influence of slip angle at braking with constant load and speed.
