Overview of Passive Isolator Types: From Classic to Innovative Vibration Isolation Technologies
Passive isolators achieve vibration attenuation through passive mechanical systems, without the need for external energy input, and are an economical and efficient solution to ensure equipment stability. This article focuses on three typical passive isolators, analyzing their technical characteristics and application adaptability.
Classic rubber isolator: a cost-effective choice
LeadTop’s hollow cone rubber isolator POT-G series uses natural rubber and synthetic rubber composite materials as the core, and expands the deformation space through a hollow cone structure to enhance damping performance. Its natural frequency of 4-8 Hz can effectively block the transmission of mid to high frequency vibrations, and the load range of 50-700 kg covers most laboratory equipment.
The product integrates precision adjustable feet and mobile casters, supporting rapid deployment and horizontal calibration, becoming a standard configuration for optical platforms, electron microscopes, and other scenarios.
Air floating pendulum vibration isolator: a powerful tool for ultra stable positioning
The ZDT-B series pendulum air floating vibration isolator adopts a single pendulum structure and ultra-thin composite airbags, with a natural frequency of 1.0-1.5Hz in the horizontal direction and 1.0-2.0Hz in the vertical direction.
By dynamically adjusting the system stiffness through an external damper, the vibration isolation efficiency in the 5Hz frequency band exceeds 88%, making it particularly suitable for laser interferometers with nanoscale positioning requirements. LeadTop incorporates an automatic leveling algorithm in this series to ensure that the equipment can maintain micrometer level accuracy even under complex ground conditions.
Porous damping air flotation isolator: high-frequency vibration terminator
LeadTop has launched the ZDT-Z series of high damping air floating isolators for vibration sensitive equipment such as coordinate measuring machines. Its multi small hole quasi laminar damping technology consumes energy through gas flow friction, with a vertical natural frequency of 1.0-2.5Hz and a vibration isolation efficiency of 80-86% at 5Hz, and a recovery time of less than 2s.
The product is equipped with a silent pneumatic system and overload protection device, balancing efficient vibration isolation and equipment safety.
From the economic practicality of rubber isolators, to the ultra-low frequency control of air floating pendulum type, and to the high-frequency attenuation of porous damping type, passive isolation technology is constantly breaking through performance boundaries. LeadTop provides vibration isolation solutions covering the entire frequency range for precision manufacturing, biomedicine, and other fields through continuous innovation.
