The x-axis points to the forward direction or the longitudinal direction, the y-axis, which represents the lateral direction, is positive when it points to the right of the driver, and the z-axis points to the ground
Tire and Wheel Coordinate Systems. The tire coordinate system axes (X T, Y T, Z T) are fixed in a reference frame attached to the tire. The origin is at the tire contact with the ground.
28 mar 2019 · The camber moment tends to turn the tire about the x-axis and tries to make the tire-plane align with the z-axis. The camber arm \(a_{y_{\gamma }}\) is proportional to the camber angle γ for small angles.
The Z axis is perpendicular to the ground plane with a positive direction downward. The Y axis is in the ground plane, and its direction is chosen to make the axis system orthogonal and right hand. Three forces and three moments act on the tire from the ground. Tractive force (or longitudinal force) F x is the component in the X direction of ...
20 paź 2011 · The lateral force F y is the force along the Y axis, the longitudinal force F x is the force along the X axis and the normal or vertical force F z is the force along the Z axis. Similarly, the moment the tire receives from the road can be decomposed along the three axes.
