how to model a system which goes down grade with constant velocity

Hi 

Thank you I found a solution. I used the step function. 

Hi,

You can either use STEP function or create an expression to impose a constant velocity. 

hi thank you what expression can i impose to maintain a constant velocity in the slope it seems to free fall 

Hi,

You can use MotionSolve API 'GCON' (general constraint). Please go through the same on help for more information about GCON. 

hi sorry to trouble you, this sounds too complex,i went through the help.where should iinput this function? should it be written in template,can u give me a example how it should be used.
1.) My condition is to make the system run with a constant velocity on the slope 
2.)how to use Gcon for the rear revolute joint in the pic so that entire system runs on a constant velocity in the slope

lets consider angular velocity of the rear wheel to be 2 rad/sec . so that it runs with the constant velocity on the slope 

thank you 

Hi,

You need to create a template in MotionView. 

I will check if there is any example available for the same. 

If possible please share the model file you have. Use the file transfer link in my signature below to share the file. 

hi prakash i have shared my files with you 

Hi,

I shared a sample model using GCON with you. Please use that as reference and let us know whether you are able to see constant velocity while rolling. /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20'> 

hi prakash 

thank you so much .That was a great work ,the example model was built with a great detail   . That model will solve my problem /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20' />
