Introduction
The type of vibration isolation is a key guarantee for the stable operation of precision instruments. Understanding the types of vibration isolation can help engineers and researchers choose the most suitable isolation scheme. This article will comprehensively analyze the types of vibration isolation, from technical principles to practical applications, providing readers with a systematic knowledge framework. Mastering the types of vibration isolation is the first step in entering the field of precision engineering.
Overview of types of vibration isolation
The types of vibration isolation can be mainly divided into three categories: active, passive, and air floating. Each type of vibration isolation has its unique technical characteristics and applicable scenarios.
classification basis
The types of vibration isolation are classified according to working principles, energy requirements, isolation frequency bands, and other dimensions. Understanding these classification criteria can help quickly locate the appropriate type of vibration isolation.
development trend
With the advancement of precision manufacturing technology, the types of vibration isolation are developing towards intelligence and integration to meet increasingly stringent vibration isolation requirements.
Types of active vibration isolation
Active isolation is the most advanced solution in vibration isolation technology, representing the highest level of isolation technology.
working principle
The type of active vibration isolation adopts an integrated design of piezoelectric sensors and drivers, which monitors and compensates for vibration in real time through an external control unit. The six degree of freedom fully active compensation technology enables it to achieve an effective bandwidth of 1.0-100Hz.
Core parameters
Response time: ≤ 20ms
Maximum correction force: vertical ± 12N, horizontal ± 8N
Product Examples
LeadTop's LVH-T15 heavy-duty active isolation platform is designed specifically for TEM/SEM, using electromagnetic actuators and four stage air spring composite technology to achieve six degrees of freedom vibration suppression across the 1-200Hz frequency range and eliminate building sway interference between 0.5-5Hz. 500kg ultra large load-bearing capacity, low-frequency attenuation> 35dB@5Hz (Corresponding to 90% isolation efficiency), 30ms step disturbance suppression, supports online modal analysis. Suitable for electron microscopy imaging, semiconductor detection, and life science fields, it significantly improves the resolution of cryo electron microscopy and FIB beam stability, making it an ideal isolation solution for heavy-duty precision instruments.
Types of air floating vibration isolation
The type of air floating vibration isolation is known for its ultra-low frequency isolation capability and is a standard configuration for high-end scientific research equipment.
technical advantage
The natural frequency of the air floating vibration isolation type is as low as 1.0-2.0Hz, much lower than other types. The multi small hole quasi laminar damping technology effectively suppresses resonance, and the automatic leveling accuracy reaches ± 0.1mm.
System Composition
Air spring isolator
Pneumatic automatic leveling system
Silent air compressor (<50dB)
Sealed suction cup (suitable for clean rooms)
Application scenarios
This type of vibration isolation is widely used in fields that require high stability, such as optical experiments, precision testing, and semiconductor manufacturing.
Types of passive vibration isolation
The type of passive vibration isolation is the most widely used solution, known for its economy and reliability.
Technical Classification
The types of passive vibration isolation include rubber damping, steel cable springs, hollow cone rubber, and other implementation methods. The natural frequency of the POT-G hollow cone rubber structure platform is 4.0-8.0Hz, and its vibration isolation performance is comparable to that of an air floating platform.
structural characteristics
Stainless steel material, strong rigidity
cost performance
As the most economical solution among vibration isolation types, passive isolation is suitable for general precision experimental environments and production line applications.
Types of hybrid and customized vibration isolation
Customized vibration isolation solutions are required for special application scenarios.
Hybrid design
The hybrid vibration isolation type that combines the advantages of active and passive technologies enhances dynamic response capability while ensuring stability.
