Sprung mass represented into Adams/View

Sprung mass represented into Adams/View

I'm trying represent sprung mass and suspension with Adams/View 2014. I put the suspension arm attached with sprung mass. I'm using the function tire. I'm not know what constrain will use at the sprung mass for represent your movement when everything has velocity. Currently, I'm using Primitive Paralellal Joint between the sprung mass and ground. I'm trying simulate only one axle.


RE: Sprung mass represented into Adams/View

One way would be to make a block running at contant speed in the x direction. Above that your sprung mass is attached to the block via vertical dof, and then join your suspension to the sprung mass. There are more concise solutions but not as easy to debug.

Can you to say what's other solutions?

RE: Sprung mass represented into Adams/View

The obvious, easiest, and most useful one is to build a full car model. The suspension at the other end can be as simple or complex as you like.

Your solution in the first post sounds like it might work if you can release the right constraints.

Another option is to fix the sprung mass to ground via a vertical dof, and then move the surface under the wheel.

The ADAMS tire is a very simple beast and is a point follower, it is lousy for ride investigations.

RE: Sprung mass represented into Adams/View

Thank's Greg. Your help has been great.
Now, I have to perform an analysis of the different road profile on each tire. How do I use road profile on one tire without interfering with the other? Or who I can create a road file? Because, when I use a road profile of the Adams library, if on one tire runs the other tire also runs the same trajectory.
