Q: The vibrations ""ran up"" the shaft of the shovel とはどういう意味ですか?
A: The vibrations (say, from the shovel hitting something, or something hitting it) traveled up the shaft. They were felt in the handle, basically. One reason for having wooden shafts instead of metal (apart from cost and availability of the material) is that wood attenuates vibrations: they decrease in strength as they travel through wood. In a metal handle, in contrast, vibrations are likely to move from the area of impact all the way to the handle at full strength.

Q: Self-excited vibration is a vibration caused by a one-way external force acting as a function of the response of an object such as displacement, velocity, acceleration. この表現は自然ですか?
A: I marked 'a little unnatural' only because there is no "or" or "and" at the end of the list! It is slightly unnatural to end a list so abruptly! It is perfect if you modify the sentence to, "...object, such as displacement, velocity, [and | or] acceleration."

I've added a comma before "such as" as a comma is used when presenting a list after it. Additionally, [and | or] means that you can pick either "and" or "or" to use in that space (but not both).
