Vibration Isolation Case Studies

DVIA-T56 re-tuning report (reference 260202R1-6) for a COXEM Tabletop SEM EM 40 at Shanghai Opotong Instruments Co., Ltd., Shanghai, China. Overview documents re-tuning due to active vibration oscillation. Vibration Specification shows N/A with the engineer explanatory note verbatim; tuning trial and tuning request match the report. Equipment condition wording is unchanged from the report. Measurement summary compares floor versus DVIA-T56 with equipment turned on. Measurement Data Obtained via UI Program publishes VC curves, Autospectrum, and Transmissibility for vertical, left-to-right, and front-to-back axes. Includes the equipment photograph from the reference report. Reference uses the standard Generic Vibration Criteria markdown table only (Word Reference EMF omitted). Decorative header imagery before the title block is omitted from the public page.

DVIA-T56 re-tuning report (serial 250102R2) for SCINCO STA 1000 at Shuyu Industrial Co., Ltd. Overview documents re-tuning due to active vibration oscillation. Vibration specification and tuning request read N/A; equipment condition matches the report wording. Measurement summary compares floor versus DVIA-T56 under turned-on equipment state. Measurement Data Obtained via UI Program publishes VC curves, Autospectrum, and Transmissibility for vertical, left-to-right, and front-to-back axes. Equipment photography was not permitted on site. Reference uses the standard Generic Vibration Criteria markdown table only (Word Reference EMF omitted). Decorative header strip before the title block is omitted from the public page.

DVIA-T78 (serial 211213R1) installation report for WONIK IPS Jinwi site, 4F wafer analysis lab. Overview: inspection of the installed isolator, Turned on/IDLE vibration measurement, and VC-curve data with Reference. Customer tool Bruker Nano Indentation tester TS77. Installation 26.04.29, tuning and vibration measurement on April 29, 2026. UI plots: VC curves, autospectra, and transmissibility by axis; §14-2 compares steady-state vibration data with data captured during TS77 image noise events. Conclusion states the isolator meets strong attenuation targets and that noise correlation points to elevated building-floor energy in 1–10 Hz rather than isolator malfunction; relocation to a quieter floor is recommended. Reference publishes the standard VC criteria table (no separate vibration-spec figure in the source form).

DVIA-T67 (serial 221012R8) installation report for Pukyong National University Yongdum campus advanced practice building, first-floor analysis lab. Overview describes post-installation tuning and vibration measurement, turned-off inspection runs, and VC-curve data with Reference. Floor vibration VC-A to VC-D by axis was reduced to VC-G on the isolator; conclusion states vibration remained below VC-F across directions and bands. Plots: VC curves, autospectra, transmissibility, installation photos; Reference table as published.

DVIA-T67 DEMO inspection and vibration report at Youngil Precision Ansan site 5F OQA room — Keyence VR-6000 3D profile measurement system. Tuning and vibration measurement with equipment Turned on/IDLE; intermittent fault analysis, VC-curve plots by axis, and Reference table.

Installation report for DVIA-T87 (serial 250922R2) at Robocube Tech assembly hall: tuning and vibration measurement with equipment installed and Turned on/IDLE. Verification covered auto-leveling under load changes and isolation performance including under applied excitation. Axis VC curves, autospectra, transmissibility, and VC reference guidance are published.
