Simulating a rotating mass in Non Linear dynamics

Question asked by Alessandro Tornincasa on Feb 22, 2016

Hi,

I would like to simulate a rotating mass in a vibrator motor that will induce vibration in a beam. Like here:

 

Vibrating Table.mpg - YouTube

 

I've created a Non Linear Dynamic simulation on attached model, but I'm not getting expected results.

As you can see from attached video, the mass doesn't rotste about the shaft axis.

 

I've created an initial velocity condition by specifying motor rpm, but it doesn't seem to induce correct motion.

Is there an alternative way to setup this study ?

 

Alex
