setup a jig that holds a frame on a vibration table and take your measreuements and then simply plug in the next frame when your done.
pretty simple test if all you want to do is get vibration results.
Have a look.

It's exactly what's going on here. You couldn't do it in a jig. it would have to have the rider on it (for proper weight) and have the wheels and tires on it, because they're a big part of the equation. Having said that, it's a completely valid approach.
Ultimately, though, it might be more expensive to take this approach.
