THE DEVELOPMENT OF A MULTIFREQUENCY VIBRATOR,
Abstract
The vibration caused by missile flight is a noise type signal consisting of many different frequency components. Ground vibration tests of missile components, however, are simple sine wave signals produced by rotating motor generator sets. To bridge this gap, the engineering group at APL undertook the development of a system to vibrate components with a multifrequency signal. The approach to the problem was to replace the motor generator sets with an electronic amplifier as a power source. An actual flight vibration tape could then be used to energize the shaker.
