same thing different name for it?

[KarmaMoon]

is a translucent bearded dragon the same as a blue bar bearded dragon, just a different name?

 

[Claudiusx]

Nope. A translucent is a beardie with a mutation causing the scales to be semi-translucent (very evident in babies as you will often be able to see their organs through their bellies, often creating a blue shade.)

A blue bar dragon isn't really a morph, as it's not a genetic mutation. It's more of a trait.
And these are often times Tigers (Which also isn't a morph) which had been selectively bred to remove more and more pattern from the back leaving the "blue bars" as the dominant feature.

Tombo is what one would consider a tiger with very high grade blue bars. Here is a picture of him as a baby and adult:
