Vibration Isolation Case Studies

Field analysis report (VOC26-049) for the DVIA-PB2200 vibration isolation system, serial 250122R1-1, supplied to Korea Institute of Machinery & Materials (KIMM). Report written date July 7, 2026. Investigates the 28 Hz peak measured on the X axis and the resonance peaks in the 50 to 90 Hz band: on-site measurement under three floor support conditions (Levelfoot with Footmaster, Levelfoot only, Footmaster only), FEM modal analysis of the isolator table top, levelness, center of gravity and noise checks, Open-Loop frequency response function, Passive transmissibility, Autospectrum, VC Curves, Active-On data, a Passive versus Active comparison, and compliance measurements at the payload support frame, pump drive structure, chamber and isolator table top and base plate. Instrumentation: PULSE 22, impact hammer and a PCB 393B05 accelerometer. 97 figures from the report are published.

YDRICQS (Quantum Science and Technology Yangtze River Delta Industrial Innovation Center, Suzhou, China) Thermo Fisher Scientific Helios 5CX FIB-SEM DVIA-ML1000 installation report — the active isolation platform meets the VC-F vibration specification on all axes (floor fails only on vertical; the DVIA-ML1000 platform passes vertical, left-to-right, and front-to-back). Per-axis Auto Spectrum and VC curves, the client tuning request form, and the installation photo are published.

Tier-1 Semiconductor Giheung NRD K-Line 4F Hitachi In-Line SEM XF-1000 DVIA-P10000 periodic inspection (VOC26-125) — measurement performed with the equipment Turned on/IDLE; vertical and left-to-right axes PASS on both floor and platform, front-to-back floor FAIL while the DVIA-P10000 platform meets the requirement on all axes.

Korea Institute of Science and Technology (Building L0, Room 184) TESCAN Clara FE-SEM DVIA-ULFB700 installation report — a revisit inspection prompted by upper-door open/close noise. The noise was traced to the spring contacting the top-plate groove with no impact on performance, and all X/Y/Z axes met the required vibration specification. Per-axis Autospectrum and VC curves are published.

Changdi New Materials Technology (Shanghai, China) Hitachi High-Tech SU3800SE FE-SEM DVIA-ML1000 installation report — the active isolation platform meets the vibration specification on all axes (floor fails on vertical while passing left-to-right and front-to-back; the DVIA-ML1000 platform passes all axes); vertical/left-to-right/front-to-back autospectrum and equipment photo published.

BIEL Crystal (Huizhou, Guangdong, China) Thermo Fisher Scientific Helios 5 FIB-SEM DVIA-ML1000 installation report — the active isolation platform meets the vibration specification on all axes (floor fails only on vertical while the DVIA-ML1000 platform passes vertical, left-to-right, and front-to-back). Vertical/Left-to-Right/Front-to-Back VC curves and the client tuning request form are published.
