Go to the hardware store and buy some locktite.  There are two types, one for frequently adjustable and one for a more permanent installation.  Get the right one, put it on your tension rods and you are all set.  No more detuning.

Yes it will, locktite was developed to prevent vibration from loosening threaded fasteners.  This stuff really works well.  

this is a lot less permanent that Lock-tite, and it will perform just as well.

Go to your drum dealer and ask for Lug-Locks.  They are small white plastic rectangles with a hole in the middle.  Get 4 of them.  Stick them on the lugs that loosen, as well as the lugs opposite.  Make sure that the plastic hits the rim of the drum.  These hold them in place so that they don't back out.

They worked fine for me...
