Automatic balance system: Adopt air servo system to automatically adjust the level. Its outstanding feature is that the response of the system to the micro-vibration is fed back to the system, the vibration isolation characteristics are changed, the vibration isolation effect is improved, and the initial equilibrium state is instantly reached under the experimental conditions of overload and heavy load Large-scale optical vibration isolation platform, the outer frame is made of high-quality medium carbon steel plate with strong rigidity, small deformation and good weldability The vibration isolation layer is made of honeycomb structure material with low natural frequency and strong vibration resistance, which can control the vibration response to the maximum extent The panel is made of stainless steel plate with high magnetic permeability, which has the characteristics of practicality, beauty and wear resistance after fine grinding Vibration isolation support adopts two-layer diaphragm airbag isolation, with high damping orifice, good and stable vibration isolation performance, easy adjustment, automatic level, automatic inflation, imported mute air compressor air source, low noise, suitable for experimental places with high vibration frequency requirements Quiet air engine air source, low noise (less than 65 dB) Flatness: < 0.05 mm/m2 Surface roughness: < 0.8 μ m Natural frequency: 1.2 Hz-1.8 Hz vertically and 1.2 Hz-1.8 Hz horizontally Amplitude: < 1.2 μ m Repeated positioning accuracy: +0.05 mm Air pressure: 0.2-0.6 (Mpa)
