Tangent...

Tangent is the obvious answer. But I assume the ultimate goal is to make it look like the wheel is rolling over the ground.

With a tangent mate, the wheel will skid along the ground when the wheel is moved.

I have not tried either of these, but it might be worth seeing if a cam mate, or a rack/pinion mate will work. My money is on rack/pinion.

If this is for a simple animation, it may be easier to skip mates, and just have the wheel transition automatically from one rotational position to the next based on its linear movement.

Rack and Pinion is a nice idea...

BTW, tangent will work perfectly if the animated car had 2 motors; one linear (for the car itself) and another rotational (for the wheels).

Motors are a good idea too. I thought an advantage of a rack/pinnion mate would be an easy link between vehicle linear speed and the rpm of the wheels.

I don't use motors often in SW, or animations. Is it possible to link the two motors so the wheel rpm goes along with the linear distance traveled?

Yup, It is possible.

But, you'll have to do it manually...

Both are good ideas...

But rack pinnion i thing is the easyest to implement in this case.

By using a fixed point (way that rack pinnion works) rotation of weel will be autoajusted to linear movement.

You just need to fix 1 motor for linear move.

hi guys I tried it only the wheel rotates but there is no linear motion takes place

What did you try?

The rack and pinion?

Please attach screenshots of what you've done...

this is that which i discuss

Which mate did you use?

I use tangent and parallel mates

Then you'll need to do as in this post...

let's assume you have three different independent parts; ground, car with shafts (for the wheels) & the wheels, if you want to see the wheels "actually" rotating on the floor, then first open the "ground" part and make an assembly of it, insert the car, then insert the wheels, first make mates between the wheels and the car shafts then make mate "tangent" between the wheels and the ground. This way when you initiate the motion analysis, choose all parts for the contact to be solid bodies, make the initial velocity for the car part, then you'll shall get what you need. Good Luck!

In order to see the wheel rotating not sliding, you will need a third part, a shaft with any shaped body (like a simple cart or something), mate the wheel with the shaft (concentric and face coincident) then you'll see it rotating.

kk I will try it

Thanks for your idea

Anytime, good luck!
