I tried to open my files in version 2024 and didnt encounter like that. 99% that the root of the problem is in tire-file. Or its interaction with road-file (maybe 3d-contact or something like that). Check again that everything is ok. And if possible, reset tire-file configuration here on the forum.
It might be worth checking "Settings - Units". Maybe degrees are indicated instead of radians?
And the entry “varval (41)....” It's also confusing. The number itself cannot be a variable.
Some formulas can be found in the attached links. Perhaps they are suitable for your comparisons.

Also may try your luck here...
I will try to speculate on a simpler example. Let's say there is no gravity or other forces. A conditional vacuum or outer space. If you hypothetically need to push an asteroid, then it is enough to apply force once, and then in accordance with Newton's second law:
"in inertial reference frames...
...by some spline.
In the case of a torsion spring, this is the angular displacement. Therefore, in the spline graph, set:
X - angle of rotation(there will be units from the settings, radians by default)
Y - moment to turn to a given angle (there will be units from the settings, N * mm by default)
I also know of only one way to create a measure - from time (run-time function). You have correctly noted that it is possible to establish dependence on another value in the postprocessor. To display multiple optimization results, try something like this:
-Create 2 measures for convenience...
Hmmm. This usually only happens if you have switched from "Template Builder" but are trying to switch back to "Standard Interface" mode. And vice versa.
Be make sure that to import the objects into the model selected template you need. After display it through menu "View - model". Now in picture only empty model
Find file ".acar.cfg" in working directory and change user mode from standard to expert (manually rewrite)https://files.engineering.com/getfile.aspx?folder=512bebd1-83a7-45f6-a6ad-101032fa4c27&file=picture.JPG
...itself, but apparently there are no variables in this model. Check all available variables by clicking in the right window of the RMB, then ADAMS_Variable >Guesses>*. To create your own variable for the measures you are interested in, you will have to use interface Adams Car Template Builder.
One of examples for Adams Car 2017:

It's strange ... This file should be automatically created / updated every time you open the Adams Car. Did your OS explorer search return no results either? Maybe the file is somewhere in the installation directory?
I don't know how important it is to calculate spline values during simulation. Why not import the data ahead of time using File - Import - Test data and then use the CUBSPL function to change the force according to that spline?
Avoid using only "FOR" or any other loops at all? You can organize, for example, through "WHILE" ...
clc
clear
z=0
while z<10
z=z+1
k = [ z+1, z^2; exp(z), z^3]
kk(z,1)={k};
end
Since for bushings and springs in Adams Car, the characteristic is set only through the properties file, then try to build and refer to the "y = x" graph. And then change Scale Factors to Adams Insight. Their value, in theory, will be equal to the stiffness
There is, of course, a very, very, very inconvenient option. Create one bin-file, and in it several models (by opening the F3 window and writing, for example, model create model = Model_front, etc.). In each of them import the left/right piece or completely the geometry, place the connections...
