Angle between IC and Ground
Angle between IC and Ground is the angle formed by the intersection of the Instant Centre and the ground line in an independent suspension system.
Symbol: ΦR
Measurement: AngleUnit: °
Note: Value can be positive or negative.
Side View Swing Arm Height
Side View Swing Arm Height is the vertical distance from the wheel center to the upper pivot point of the swing arm in an independent suspension system.
Symbol: SVSAh
Measurement: LengthUnit: mm
Note: Value should be greater than 0.
Side View Swing Arm Length
Side View Swing Arm Length is the distance from the axis of the coil spring to the axis of the wheel in an independent suspension system.
Symbol: SVSAl
Measurement: LengthUnit: mm
Note: Value should be greater than 0.
tan
The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle.
Syntax: tan(Angle)
atan
Inverse tan is used to calculate the angle by applying the tangent ratio of the angle, which is the opposite side divided by the adjacent side of the right triangle.
Syntax: atan(Number)
