Defines a Steer Axis.
 
For the option:
Do the following:
Steer Axis Calculation
Select a method of calculating the steer axis:
■Instant axis - Requires one part and one hardpoint. When using this method, it is very important that you select the correct part and hardpoint information. You can use any part and hardpoint, provided that locking the vertical motion of the part at that hardpoint location actually locks the spring travel. Learn about Hardpoints.
■Geometric - Requires two parts and two coordinate references. Adams Car creates markers that belong to the specified parts at the desired location (the ones defined by the coordinate references). Learn about Markers.
The geometric method is more intuitive, but sometimes is not applicable (for example, in a suspension where the geometrical information that defines the steer axis is not obvious; where it is impossible to identify the position of the steer axis).
Note: Both methods give accurate results, but the instant axis is more general, because it can be used when the steer axis cannot be determined geometrically (for example in a multi-link suspension).
Suspension Type
Select a suspension type:
■Dependent - Select dependent for a driven, solid axle suspension, where the suspension reacts the drive-torque input to the differential pinion gear.
■Independent - Select for all other supensions.
Adams Car uses this information when calculating the squat and percent anti-squat.
If you set Steer Axis Calculation to Instant Axis, Adams Car displays the following options:
Part
Specify the part you want to use in the definition of the steer axis.
Coordinate Reference
Specify a Coordinate Reference to define the location where Adams Car locks the spring travel.
If you set Steer Axis Calculation to Geometric, Adams Car displays the following options:
I Part
Specify the first part to use in the definition of the steer axis*.
J Part
Specify the second part to use in the definition of the steer axis*.
I Coordinate Reference
Specify a coordinate reference to define the location where Adams Car creates the first marker (belonging to part I) used in the definition of the steer axis*. This coordinate reference also defines the Kingpin Location.
J Coordinate Reference
Specify a coordinate reference to define the location where Adams Car creates the second marker (belonging to part J) used in the definition of the steer axis*.
 
Note:  
* For geometric, the steer axis is the line connecting the two markers at the location specified in the coordinate reference field.
