  • Using ADAMS/CAR calculated acceleration as input to a NASTRAN model

    Hello, I am looking at extracting accelerations on the body to be used as input to FEA (NASTRAN) body to calculate the stresses. Acceleration is calculated at the chassis. I am running the model on digital tracks and using F-TIRES. I am…

  • The switch part has also influce on the dynamic results ?

    Hello Everyone, I built two suspension templates. The only one difference is with and without Switch Part . Meanwhile the topologieplan between them is the same. That means, force or/and joint elemnt connect always between A part and B…

  • Is it posible to get the Positions of the Hardpoints in a resultfile?

    Is another specified Request necessary?

  • How do I process Adams projects externally (command line or Matlab/python)?

    I am trying to process Adams from either the command line or Matlab/python interfaces. I am looking for documentation that could help me with the following steps: Opening Adams Creating a project Importing and running CMDs Importing…

  • BCs for flexbodies

    Hello, Is there a way to include SPCs in your model when creating and MNF file for a flexbody? I am asking because when I tried creating an mnf file for a table-like structure, the 1st mode was completely off than when running a simple sol103…

  • How can I control the value of a "Parameter Variable" during the simulation?

    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…

  • Looking for a way to develop actuator displacement signals on an Adams rig capable of reproducing measured responses on a test (physical) vehicle. Any suggestions for tools or processes?

  • cnfsub loci and locj

    Hello, I'm trying to build a subroutine for a custom contact normal force. I require the locations of the contact so I wanted to utilize the loci, locj variables but every time print their information they seem to be completely off. To elaborate…

  • How to model contact between flexible bodies, by using primitive geometries in place of flex to flex contact?

    Hi, I am trying to modify a contact between flex bodies in my model to reduce the simulation time by modeling two cylinders and fixing them to the bodies and defining the contact between these two cylinders. But once I modify the contact between the flex…

  • Integration over a variable (not time)

    I have a column of an oil and gas mixture, where gas-to-oil ratio varies along the height of the column. The ratio also varies with time. To get the total amount of gas in the column at any one time, i would like to integrate over the volume (height…

  • How can I control joint forces in Matlab?

    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…

  • How to Create a Clutch System for an Attachment in Matlab-Adams Car Cosim?

    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…

  • Adams - scFlow Cosimulation with flexible bodies

    Hello, Is it possible to use flexible bodies in Adams - scFlow cosimulation? e.g., If I wanted to simulate a UAV during flight, could I model the UAV's outer shell as flexible body? If so would the wall force from scFlow get transferred…

  • Is it still possible to access the old user forums? I have questions that I'm sure have been answered on those forums.

  • I am trying to generate a request for angular momentum, so I have a measure for angular momentum of a body, but then when I reference that measure in the requests (define using function expression) it doesn't register and it just outputs 0.

    How can I fix this? I'm using Adams 2021.3.

  • Get the action time of senor

    Hell everyone, I make one seonr to monitor the angle of robort arm. Now I try to make the arm stop with function(step) when the seonsor is active. I think there are wrong about the time setting in the function. Should I get the action time…

  • Flexbody constraints

    Hello, I want to constrain a flexible body on multiple points, using rbe2 and fixed joints. When I use more than 1 joints I get a redundunt constraints message and the simulation stops due to lock errors. I tried removing some of the fixed…

  • Is it possible in adm the design variable is in usage ?

    hello everyone, Coule I ask , is it possible in adm the design variable is in usage ? For example, I assign one design varialbe to define the spring stiffness, then expert adm and acf for file only simulation. Background: I want to change…

  • Macro to create markers at a fixed location in multiple identical objects.

    I have multiple identical objects (pistons) in my Adams model. I want to create a marker at the center of back face in each piston. ( as seen below) I want to know can I automate this process using some macro. (The location on highlighting…

  • Finding expression AX(x,x)

    I needed to rotate part of my model by 90 deg. Luckily, i did build this part around 1 ref point, so by rotating that point the whole part rotated by 90 deg. Now i am getting the following warning , which says some markers are 90 deg out of…

  • Scripts for model auto-generation

    Hi Folks, Here is part of my script for auto-generation of force in a model. 1- variable create variable_name=n integer_value=1 2- while condition=(n < (eval(total_roller_number+1))) 3- force create direct general_force & 4…
