Abstract:

Vibration testing was conducted to determine the recording characteristics of the recorder when mounted with and without isolators and subjected to a vibration environment. The vibration test program was conducted in 5 phases. Test Phases 1, 3, 4, and 5 were conducted with the specimen mounted to the vibration fixture via vibration isolators and test Phase 2 was conducted with the specimen rigidly mounted to the vibration fixture. Low-level 2g peak sine survey tests with the tape recorder not operating were conducted on the tape recorder during test Phase 3, and full-level 10.5g random vibration tests with the tape recorder operating were conducted on the tape recorder during test Phases 1, 2, 4, and 5.
