high frequency vibration testing. typical electrodynamic shakers have a usable frequency range up to 2000-3000 hz. for higher frequency applications ud engineers have developed two different shaker systems optimized for sine & random vibration tests up to 5000+ hz. and extreme srs shock events out to 10000 hz.!. h560bac/2
getting more out of my sub ken cranes and a local high end audio store i purchased a velodyne spl-1200ii. the second way is to buy a test cd that has frequency test tones and check out
in the current family of vibration research shakers the vr4600 is one of the largest. the large diameter armature adapts to many test requirements with a minimal amount of fixturing. high lateral and axial stiffness decrease problems associated with off-center loads. unsupported horizontal operation is possible on many loads.
