Hi,
I would like to create five link non-steerable suspension for the rear axle. I'm not sure how to deactivate/switch tie rod to trailing arm. Could anyone please help me how to do this?
Thanks in advance!
There are two undocumented functions we're considering removing from Adams Car 2018: READ_SETUP() and WRITE_SETUP(). In the Adams Car product, we never use these functions. If you use these functions in your work, let us know here!

Hello,
I'm creating a flexible suspension subsystem from a rigid subsystem. It involves replacing the control arms and the subframe with MNF files which has been carried out successfully. Next step is to adjust the subsystem to tune the wheelbase…
Hello everyone,
I am trying to better understand how are outputs from suspension assemblies computed. But in help about Lift/Squat Acceleration i do not undestand to this part:

I need to include a Racing Track Kerb into a 3D flat road or another 3D road that has part of it flat. If you have a script/tool to do it and you can share it, let me know. Any ideas on how to do it are welcome
Thanks

I had the crazy idea to use the RT Solver to speed up a set of analysis (using FTire and dtout=1e-3 s)
So I tested the MSC Demo vehicle for one typical case and found the benchmark time was 2:05 min for everything on default settings.

Hi All,
I need to modify the EV Powertrain from 2 motors (1 front and 1 rear) to 4 motors (1 at each corner).
I have a few ideas how to maybe do this.
A 'long' way is to modify the existing template by building left and…

I want to use an acar model including default actuator and transducer property files. The model is stored in a binary file to give a quicker opening of the model when I do a design study. The problem is that when I do my analysis full vehicle submit,…
Hello, I want to model a simplified EV powertrain with a single stage reduction without clutch. I have a powertrain pedal map(Throttle vs Rpm vs torque) I wish to define. Simple proportional Torque option does not help, kindly suggest a way
I'm developing a macro that runs a combination of SPMM events, and I need the model name and variant of a currently open model. I know I can retrieve the model name via (EVAL(DB_DEFAULT(system_defaults, "model""), but I can't do the same to get the variant…
I'm trying to run a cosimulation with an A/Car model with Simulink as the master. My A/Car model use some subroutines that is included in our site solver, but the cosimulation use the standard solver. I have tried to use the "User Defined Library Name…
In the distant past, Car models could define flexbody interface parts with mass properties. There's no user interface for such a use case, so we're considering dropping support for these in the subsystem file.
Any objections?
I need to control a parameter variable during the simulation. For example, when a state variable exceeds 1, the specified "Parameter Variable" is 1. On the other hand, when the state variable is lower than 1, the specified "Parameter Variable" should…
I would like to control the joint forces (no need for torque) in Adams Car-Matlab cosim. For example, a joint force in x, y, and z directions are 50, 150, and 200 N, respectively. When I use the gain function in Matlab, I would like to be able to make…
Dear all,
Rightnow I am going through one problem and that needs to investigate as soon as possible.
I have optimized the hardpoints to get the desired steer angles for 85mm rack travel at suspension level.

Hello,
I was wondering if there was a way to force an infinite analysis duration within Adams Car. My intent is to perform a simple analysis, such as straight-line maintain on flat, 2d road, but tell the solver to run until told to stop, so that…
Hi guys, I am was trying to create an Baja ATV in Adams car. During acceleration analysis I get Toe out in front suspension geometry and it got steer itself even the steer input was locked. I was trying constant radius cornering and its getting failed…
Hi,
