Abstract
The present vibration test module enables a test engineer in the field of vibration test systems to precisely implement a vibration environment that is applicable to a wide range of applications and performance characteristics. The vibration test module comprises adjustable vibration shaping elements that collectively function to enable the user to program the frequency and magnitude of the vibrations that are produced by the vibration test system. This energy redistribution is accomplished by providing tuned vibration absorbers, consisting of a bouncing mass enclosed in a housing having walls that are elastic and/or spring mounted and/or adjustable in position, which enable the test engineer to precisely shape the frequency response of the vibrating system by causing broad band vibration to be generated in the vibration test system by the series of impacts of the mass with the walls of its enclosure.
