| Description |
A multipoint excitation system for resonance testing of13; complex structures is described. The system can be used to power upto 6 shakers of 20 Kg. force capacity, over a frequency range of 5 Hz to 500 Hz. Two sets of power amplifiers, one for low level, and one for high level drive, form the basic source of drive power for the shakers.Control equipment consist of preamplifier's and phase shifters for each of 6 channels; measuring equipment include a vibration meter and force measuring unit. The control and measuring equipment are all housed in a mobile console which contains all the opening controls for the system.
