A Sub-Seismic Test Platform as a Motion Exciter.

Abstract

The technique and use of a large pneumatically supported test platform as a motion exciter is described. Maximum motion capability, and the effects of system resonances of the 450,000 lb, servo controlled, isolation test platform is shown for use in tests of motion sensors (e.g., inertial navigation gyros and accelerometes, seismometers, and tiltmeters). The possibility of large test specimens, such as a complete navigation system, is considered. Information is provided on the construction of the test platform and the electropneumatic control system which maintains the test platform level to 0.001 arc seconds and free of vibrations greater than 10 to the -8th power g.
