1 (X):  Left Wheel Front View Swing Arm Length

mm

The distance between the left wheel center and the left wheel center front view instant center.  It is calculated using the following equations:

Orientation A:

dy = C(2,3)-C(2,9)

dz = C(3,3)-C(3,9)

dtheta = C(4,3)-C(4,9)

length = sqrt(dy^2+dz^2)/abs(dtheta)

Orientation B:

dy = -C(2,3)+C(2,9)

dz = C(3,3)-C(3,9)

dtheta = -C(4,3)+C(4,9)

length = sqrt(dy^2+dz^2)/abs(dtheta)

2 (Y):  Right Wheel Front View Swing Arm Length

mm

The distance between the right wheel center and the right wheel center front view instant center.  It is calculated using the following equations:

Orientation A:

dy = C(8,9)-C(8,3)

dz = C(9,9)-C(9,3)

dtheta = C(10,9)-C(10,3)

length = sqrt(dy^2+dz^2)/abs(dtheta)

Orientation B:

dy = -C(8,9)+C(8,3)

dz = C(9,9)-C(9,3)

dtheta = -C(10,9)+C(10,3)

length = sqrt(dy^2+dz^2)/abs(dtheta)

3 (Z): Average Front View Swing Arm Length

mm

The mean of components 1 and 2.

4 (RX):  Left Wheel Front View Swing Arm Angle

deg

The front view angle between horizontal and the line connecting the left wheel center and the left wheel center front view instant center.  It is calculated using the following equations:

Orientation A:

dy = C(2,3)-C(2,9)

dz = C(3,3) - C(3,9)

angle = -atan(dy/dz)*rtod

Orientation B:

dy = -C(2,3)+C(2,9)

dz = C(3,3) - C(3,9)

angle = -atan(dy/dz)*rtod

5 (RY):  Right Wheel Front View Swing Arm Angle

deg

The front view angle between horizontal and the line connecting the right wheel center and the right wheel center front view instant center.  It is calculated using the following equations:

Orientation A:

dy = C(8,9)-C(8,3)

dz = C(9,9) - C(9,3)

angle = atan(dy/dz)*rtod

Orientation B:

dy = -C(8,9)+C(8,3)

dz = C(9,9) - C(9,3)

angle = atan(dy/dz)*rtod

6 (RZ): Average Front View Swing Arm Angle

deg

The mean of components 4 and 5.
