Hello everybody
Can anybody tell me difference of vas_steering_demand value in postprocessor with different solver settings (Gstiff/I3, Gstiff/SI2, HHT/I3)
All simulations are done as DLC with speed 50 km/h with (MDI_Demo_Vehicle)

Hi, is somebody having same issue? Exporting fmu when dcf file is stored in private database (i.e. just coping acceleration_dcf.xml from shared database) for me i am always having this error:

Hi everybody, i want to reorient full vehicle assembly (MDI_demo_vehicle) in Adams 2023.4.1, i want to rotate vehicle (180,180,0).
I have tried all combination to use or not (Keep Current Road Position, Retain Parametrization) but after rotation…
Hello everyone,
I am trying to run older model (2010) into newer version of Adams (2017.1) and getting following error message related to ftire (cosin 2017.1).
I have tried running with PAC tire and it works fine. So, looking for…
I have been working on damper optimization analyses. I have prepared varying damper files to combine in Adams Insight. I have tried many different test-rig. Knowing how objectives and their equal value in the postprocessor differ in a four-poster analysis…
I couldn't find any example without .adm file for optimization in Adams/Insight Ascii. What I need is to use Adams Car and Adams Insight Ascii to optimize damper (.dpr extension) values.
I've created a leaf spring using "Leaf Spring Editor". However, I've been struggling to draw its Load/Deflection diagram. For that purpose, which parameters should I use in x-axis and y-axis in the postprocessor interface?
For instance, I've…
Hello everybody,
I tried to simulate a bevel gear with the simplified method in Adams/Car 2019 on a Windows system. Unfortunately the simulation couldn't be started due to a library error. I also tested an example from the shared database …
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…
I want to make ARB noneffective dependent on a state variable. Whether it should be active or nonactive, changing with the value of the state variable. It would be amazing to provide zero effect (for the specified joint) in Simulink, but I am open to…
Hello everyone,
I have model of vehicle in Acar. Models works fine in Acar (no warning message,), but if i want to use it in Simulink the simulation ends with Error in supplied FMU: An error occurred in function 'fmi2ExitInitializationMode…
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,
I tried acceleration analysis in my custom vehicle assembly, and while analyzing the vehicle turn automatically and analysis gets failed. I don't know why its happening. Can someone help me to solve this problem.
Thanks in advance
Attached…
I was trying to do an Baja ATV full vehicle assembly analysis in Adams Car, but i get problems while trying to do the analysis as shown in the image. Even though the tire template was a default tire model that was given in acar shared template and other…
Hello, I want to make request same as 907 (measuring displacement) but with functions:
My request using functions:
To obtain same translational displacement for F2 i had to add minus sign:
Problem is with angles. Yaw angle values…
Hello everyone,
I have model of vehicle in Aview created according templates from Acar. Model is working without problem. The model in Aview contains also requests from Acar (i.e. from rigid chassis.tpl based on subrutine abgVDM::req907). During…
Hello everyone, can some explain me how is brake demand outputed from testrig to brakes subsystem from shared directory.
Help says:
The torque on the rotor depends on a number of parameters. The front right torque function is:

Hi, i was trying front suspension analysis, but i don't know what i had mistake but my wheels are not moving when the test rig moves. And also i get some error like this
"acar/RIDE

Colleagues,
I'm trying to model a testrig with operation similiar to 12DOF suspension testrig, where ALL wheel loads are attached to wheel hubs, for performing durability simulations close to real laboratory testing, and, also, load signals…
I am trying an H-arm Camber link suspension type, but I get an error like this "Static equilibrium analysis has not been successful". I checked the constraints with other templates but I couldn't find mistake I had done. Can someone please help me to…
Hello everyone,
I do not understand why adams car computes moment of inertia in different way than adams view. If i understand correct Adams view as default uses cm marker for both cm position and orientation. According geometry view orients…
Hello,
Can you give me some advice about my results of comparison. I wanted to compare double lane change with some maneuver as open loop. I did it this way:
I have created Double lane change simulation.
In PPT i saved data from…
