Vibration Control of Piping Systems Published in Gas Compression Magazine

DEICON was featured in the December 2025 issue of Gas Compression Magazine with a technical article focused on vibration control in industrial piping systems. The article addresses how operational forces such as flow turbulence, compressor‑induced excitation, and two‑phase flow can trigger resonance in piping, leading to fatigue, reliability issues, unplanned downtime, and potential safety concerns […]

Cycling Studio Floor Vibration Control Using Tuned Mass Dampers

In an indoor cycling studio where up to 40 riders pedal rhythmically at about 60 rpm, staff noticed excessive vibration—particularly near the reception desk, located at the mid‑span of one of the long‑span bays. Numerical modeling and on‑site measurements revealed that the floor’s first natural frequency of 4.3 Hz aligned closely with the harmonic forces […]

Vibration Control of a Balcony in a Music Venue/Theater

In a new 2,150‑capacity, state‑of‑the‑art music and event venue, engineers sought an effective solution to mitigate rhythmic, audience‑induced vibrations in a 3‑sided, 270‑degree wrap‑around balcony. Because dynamic loads from concertgoers can cause noticeable vibration—particularly near mid‑span and edge regions—this project required a damping approach that preserved both comfort and architectural openness. To meet this challenge, […]

Transformer Noise (Hum) Reduction by Air Isolation

DEICON implemented an air‑isolation vibration control system to dramatically reduce transformer hum in a 3300 KVA transformer installed on the penthouse level of a 16‑story corporate office building. The transformer’s tonal noise—primarily caused by magnetostriction of the core laminates, producing strong vibrations at 120 Hz and its harmonics—was transmitting through the floor into executive office spaces below. […]

Monumental Staircase Vibration Abatement Using Tuned Mass Dampers

DEICON recently mitigated pedestrian‑induced vibration issues in a monumental staircase at a healthcare educational facility by installing three tuned mass dampers (TMDs) calibrated to the staircase’s first bending mode. Before installation, DEICON performed vibration measurements to confirm the natural frequency and inherent damping. After tuning and commissioning the TMDs, damping in the target mode increased […]

Hydraulic Cylinders Configured as Viscous Damping Devices

Connecting the two sides of the piston in a double-acting, double-rod cylinder through an external adjustable flow control needle valve, transforms the cylinder into a fluid viscous damping device (VDD). Vibrational motion prompts the fluid to transfer from one piston side to the other via the flow control valve, dissipating vibration energy due to the […]

Gymnasium Floor Vibration Mitigation Using Tuned Mass Dampers

In modern gymnasiums, floor vibrations caused by various activities can be a significant issue, particularly when the gym is situated on higher floors of a multi-story office building. DEICON recently addressed this challenge by supplying two tuned mass dampers (TMDs) to mitigate vibrations in the floor system of one such gym on the 2nd floor […]

Active Boom Noise Abatement in a Sport Utility Vehicle (SUV)

Large vehicles, such as sport utility vehicles (SUVs) and minivans, exhibit body boom phenomena during multiple source excitation events including rough road/impact and power-train induced events. The main cause of the boom is the low-frequency acoustic/vibroacoustic standing waves (modes) of the cabin cavity being excited via the high acoustic transfer functions at multiple paths, due […]

Vibration Control of Long Span Balcony in a Church Using Tuned Mass Dampers

Upon having the construction of a new church near completion, walking induced vibration was perceived on a long span balcony. DEICON conducted on-site measurements and identified the first two natural frequencies of the balcony. In addition, the participating mass and the damping ratio of mode 1 of the balcony were evaluated. DEICON designed and fabricated […]

Vibration Isolation System for a Large Industrial Process Equipment

DEICON designed and fabricated the components for vibration isolation of a massive 110,000 lb, industrial process equipment, subject to random perturbation. The isolators used in the random vibration isolation system are made up of low-stiffness coil springs paired with viscous dampers. Motion control schemes were incorporated into the isolation system to manage the lateral excursion […]
