From Principle to Practice: Introduction to TMC Passive Vibration Isolation Products

In the first three articles, we gradually uncovered the "veil" of vibration and isolation: first, we recognized that vibration is the "invisible killer" of precision equipment, then mastered the "physical examination" method of environmental vibration through VC curve, and finally delved into the principle and key parameters of passive isolation. The value of theory ultimately lies in practice. Today, we will focus on TMC's core passive vibration isolation products and see how these "vibration filters" transform the isolation principle into tangible stability, providing protection for precision equipment in different scenarios.

Based on the core design logic of 'low natural frequency+precise damping control' for passive isolation, TMC has developed various damping levels of air floating isolators to meet different isolation needs in high-precision fields such as semiconductors, optics, and life sciences. TMC can provide customized vibration isolation solutions for nanometer level lithography processes, micrometer level cell observations, and atomic level surface analysis.

1Gimbal Piston air flotation isolator-High performance vibration isolationpreferred

Core Technology:Dual chamberLow stiffness air spring+precision damping hole design

BelowShowcased TMC's Gimbal Piston Sectional view of the isolator.Adopting a dual chamber design, the two chambers are connected through precision small holes. When the piston moves up and down, air flows through the small hole to generate damping force, achieving intelligent adjustment of strong damping for large displacement and weak damping for small displacement. This not only ensures fast stability, but also does not affect the isolation effect on small amplitude vibrations. This type of isolator has a damping factor Q ≈ 3 at a displacement level of approximately a few millimeters.

TMC'sStandard air flotation platforms are usedGimbal Piston®air flotationVibration isolators are standard equipment. In parallel testing, the performance of Gimbal Piston has consistently outperformed othersair flotationVibration isolator. It has excellent low-frequency isolation performance on all axes, and can maintain its performance specifications even at extremely low input excitation levels. The proprietary vibration reduction technology enables Gimbal Piston to stabilize heavy and light payloads, and quickly eliminate interference from the isolation table.

It has a slight damping characteristic, high responsiveness to typical low amplitude ground vibrations, and can achieve excellent vibration reduction effects for severe transient disturbances such as sudden load changes or roof impacts. The results indicate that the Gimbal Piston isolator can provide vibration isolation and eliminate any severe interference within seconds. It can also stabilize an isolation system with a relatively high center of gravity without affecting the isolation effect.

Advantages:

Vertical and horizontal isolation starting from 2 Hz

Vibration at 10 HzattenuationOver 95%

Almost frictionless, avoiding the transition from rolling friction to static friction

Adjust horizontal displacement by acting as a universal joint

2. MaxDamp High damping isolator: the "dual" of resonance and disturbanceRe guarding”

TMC's MaxDamp isolator adopts different methods: multi axis viscous fluid dampingThe isolator uses a synthetic oil with extremely low deflation and high viscosity, which is sealed in a single chamber of the isolator. The special geometric structure ensures that the isolator can dampen vertical and horizontal movements (in both X and Y directions) with the same efficiency. These isolators can extend damping to near critical levels to meet applications that require this characteristic. The MaxDamp isolator allows the payload to stabilize very quickly after worktable movement, while still providing significant vibration isolation.Through the "high damping design", a perfect balance has been found between resonance suppression and isolation efficiency. Suitable for high force, high-speed XY electric workbenches that require fast and stable payload.for exampleSemiconductor testing, lithography machines, and other instruments with relatively high power electric workbenches.
