Abstract
A process and an apparatus for testing spring elements includes supporting at least one first spring element between first arms of a pair of lever beams, each having a stationary bearing, and at least one second spring element, between second arms of the pair of lever beams, and cyclically oscillating at least one of the lever beams at a frequency which essentially corresponds to the first resonant frequency of the oscillatory circuit formed by the lever beams and the spring elements, and the lever beams being oscillated in phase opposite to each other.
