When i press “Record simulation”, nothing is happen with the original animation. In all of the tutorial from Ragdoll YouTube channel its works, but in my situation its doesnt.
What i should to do? 
Hi @Dskoropanov, welcome to the forums! 
Looks like the recording didn’t finish due to some error, there may be a message in the Script Editor about what happened. Are you able to copy/paste it here?
Also keep an eye on that green bar towards the bottom, the yellow dots are the frames that Ragdoll managed to simulate, the others were skipped because the Maya playback is skipping frames.
Recording will not skip frames, so the result you see will be different, unless you play with “Play Every Frame”.
