Hello,
can someone help me to figure out which units the damping curve has on the x- and y-axis . I also tried to change the values of the rear damper curve, but if i insert my own value a formula appears and its not possible to change the value like i want it to.
Best regards
Kay Steinbach
Hello Kay
I presume the Damping Curve is being referred into a SpringDamper or a Bushing entity. So, then the x units should be length_unit/time and y unit should be force_unit. The length_unit, time and force_units should be as per the settings in the Solver Units Dataset.
Below is the Solver Unit setting example which is the default.
So if this is the unit settings, x unit will be mm/sec and y unit will be Newton.
You have not attached any model, so, it is hard to guess what is being referred as rear damper curve. Could you share the model and any reference files that is being used by the model ?

Hello, sure i can provide any data you need, thats no problem. i attach the model so you can see the rear damper curve, i hope you you might be able to understand whats my problem with the values is.Best regards Kay
Thanks for the model Kay. So here is how this damping curve is defined.
When you click on any field, what you see is a raw expression entered. e.g the 3rd point Y has an expression -2400-1200, (which comes to -3600).
Then there is a scale defined for X & Y. Y scale is 0.175
So the evaluated value comes to -3600*0.175 = -630. And that is what is seen when the field is inactive.
To modify the values, either you may factor in this scale. or change the scale to 1 and put in the exact values you wish to use.
You may also change the method of input for the Curve to a File or Math. In case of file, you can provide a csv or txt file.
Hope this helps.
