SEMMSS (Systems and Equipment Maintenance Monitoring for Surface Ships) Accelerometer Mount Transmissibility Evaluation

摘要

Alternative accelerometer mount configurations were vibration tested and compared for transmissibility in the primary frequency range of interest from 0 to 10,000 Hz. Data are also shown up to 12,800 Hz. Candidates tested include four adhesives, one magnetic base with and without silicon grease, one mechanical bayonet connection, and a base-case threaded stud connection. The adhesives were tested only after 24-h exposure in water at 160 deg F and 24-h exposure in oil at 120 sup 0 F. The transmissibility of all candidate mounts is compared with the base-case threaded stud mount. Candidate mounts are ranked according to overall performance. (ERA citation 12:029174)
