Motion in belt-pulley-simulation

Altair Forum User

Hello,

 

i tried the new belt-pulley-simulation in MotionView.

The assembly was correct and i attached a rotary motion to the first pulley.

In the animation can be seen that this pulley ist rotating, but not the belt and other pulleys.

Is there an option for friction or others necessary settings?

 

Thanks and greetings

Hi Pierre,

 

How the belt and pulley are connected?

 

Is it possible to share the model file?

Hello Prakash,

they are connected with ball joints. That is the specification in the sample.

I have attached the model-file.

Hi @Pierre

 

It took so long to complete the analysis.

 

So, I can see the pulleys moving. Maybe you should increase the simulation time.

 

 

Altair Forum User

Which simulation time did you choose?

 

I wanted the simulation end time set to one turn of the great pulley. Maybe its to short.

I am attaching animation video of the results where the pulleys are rotating (slightly) and belt is also moving.

 

Confirm if you are seeing the same.

Yes, there is a slightly movment.

In my animation the three pulleys are jerking.

I have start an new run with an end time of 0.16. Befor was 0.013.

I keep you updated.

now, its working.

 

thanks for the tip with the longer simulation time.

 

greetings
