Vibration testing, particularly when performed in reliability test chambers, is very costly. Discussed in this report are design considerations for a vibration test platen which will accept several test specimens for simultaneous testing. Well designed platens will provide more meaningful results and reduce test time and costs through maximum utilization of test hardware. Specific points covered are Bending modes at the platens frequency Determining the resonant frequency of a test platen Determining the damping energy of a platen design Obtaining signal feedback for vibration control purposes Deriving equations for resonant frequencies and damping energies.
