Circular trajectory

Altair Forum User

Hi to everybody,

i need a help for this type of situation please: i've imported a circular curve in MotionView and i want to use it as a  plane trajectory for my model. Which type of join should i use? and how should i set the motion? thank you

HI,

What I understood is that you have a angular motion and you want to convert that to translational motion, correct?

 

Think about a slider crank, an angular motion is applied which is converted to translation motion. Here not one joint or body is involved but more than one. 

 

So it depends on what you are modelling.

oh no im sorry @Prakash Pagadala, maybe i wasn't clear, i,m so sorry

My main aim is to check the stability in curve of a wheelchair, so i've thought to create a circular trajectory (as i said in the first message of this topic) and move the wheelchair  on that, but the problem is the type of the joint between the wheelchair and the curve. Thank you and sorry again for the mistake.

Hi @FP90

I am able to partially imagine the scenario. May this tutorial can help you MV-1026: Modeling Curve-to-Curve (CVCV) Higher-Pair Constraint /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20'>

@Prakash Pagadala thank you for you help, it was very helpful.

I have another question: i want to write a type of constrain Constraint_UserConstr  using Matlab and not a dll file. Is there any example that can show me ho to write the script in matlab? Bacause i have found only how to write the XML file, the following one.

Thank you
