Vibration Isolation Case Studies

Safran Transmission System LAB, Colombes — JEOL JSM-IT800 on DVIA-ML1000 (250829R2).

DVIA-ML1000 installation report — Beijing University of Aeronautics and Astronautics Unisoku STM (serial 250730R1-1). Overview documents Z-axis VCM issues (Dec 3 / Dec 11 visit), interim tuning with Z2 off and Z3/Z4 matrix sign reversal, and acceptable overall performance with slight horizontal-axis degradation pending full VCM repair. Transmissibility plots (vertical, left-to-right, front-to-back), tuning-request capture, and equipment photo.
