Braking in Adams/view
Braking in Adams/view
(OP)
Hello,
I´m new here, so i try to describe my problem as good as possible. My problem is that i have to simulate RC car chassis on my school project. I only have adams/view and i´m using PAC2002 tire model. On each wheel i get rotational joint motion with velocity formula using STEP5 function: STEP5(TIME, 1,10/0.03, 4,5/0.03).
The initial conditions have to be 10 m/s. Unloaded radius is 0.03 m. I don´t know how to make a bigger friction cause everytime there is a big longitudial slip and velocity for example of baterry is in 5 sec only about 9,1 m/s.
Could someone tell me what i´m doing bad? Is there any other solution have to brake the car using Adams/view?
Thanks for all help, cause i´m starting to be hopeless.
Sorry for my english.

RE: Braking in Adams/view
That's not really a very good way of braking a wheel, real brakes apply torques.
However, more likely you haven't switched friction on between the wheels and the ground.
Click contact, select a wheel, select the ground. Then switch friction on and set it to 1.
There are many other problems with what you are trying to do, I suspect.
Incidentally I strongly suggest you do the Latch tutorial in the getting started guide.

RE: Braking in Adams/view
Also I try the Latch tutorial as you say. How can I apply torque when the step function is not the best way to do it. Sorry for my question.
Thank you for help

If the tir file is from a real tire it probably has enough friction already.
