The Response Of Vibration Mounts Subjected To Biharmonic Vibration, Paul H. Adams Jan 1956

The Response Of Vibration Mounts Subjected To Biharmonic Vibration, Paul H. Adams

Mechanical Engineering ETDs

Existing specifications used in vibration testing are based on envelopes of many points of fixed frequency and vibration amplitude measured at specific points in aircraft. In addition these specifications are to some extent written to be compatible with the two common types of vibration test machines, the reaction or constant-displacement type and the electromagnetic or constant-acceleration type. Thus the "envelope" of the measured vibration amplitudes is drawn in such a manner as to have a constant displacement from 3 to 60 cycles per second, the range of the reaction type of vibration test machine, and a constant acceleration from 60 …
