In precision manufacturing, optical inspection, and other fields, vibration interference is a critical factor affecting equipment stability. Passive isolators absorb or isolate vibration energy through physical structures, achieving efficient vibration reduction without external power sources. This article analyzes how to precisely match isolation solutions to application requirements based on selection logic, integrating LeadTop's four core product lines.

Core Principles for Passive Isolator Selection: Identifying Vibration Sources and Equipment Requirements

Selecting passive isolators hinges on three core parameters:

1. Vibration Frequency: High-to-mid frequency vibrations (e.g., ground traffic, equipment operation) require high-damping materials for rapid energy dissipation; low-frequency vibrations (e.g., foot traffic, wind-induced vibrations) demand low-natural-frequency structures to suppress resonance.
2. Load Capacity Range: Select individual isolator load capacity based on total equipment weight to prevent structural failure from overload.
3. Installation Space: Compact equipment requires low-profile isolators; mobile applications necessitate casters or self-leveling features.

Passive Isolator Application Scenarios: Four Series Cover All Needs

Mid-to-High Frequency Vibration Scenarios:

LeadTop's POT-P Series Solid Rubber Isolators utilize a composite rubber structure with vertical natural frequencies of 6.5-12Hz and horizontal frequencies of 3-8Hz. Their damping ratio ranges from 0.05 to 0.2, making them suitable for medical and biological applications with lower vibration requirements. The height-adjustable base enables precise ±5mm leveling with a recovery time <5 seconds, balancing stability and convenience.

High-Precision Low-Frequency Applications:

The ZDT-Z Series high-damping air-float isolators utilize ultra-thin composite airbags and multi-pore quasi-laminar flow damping technology to reduce vertical natural frequency to 1.0-2.5Hz. They achieve 80-86% isolation efficiency at 5Hz with a recovery time <2s, meeting ultra-low-frequency isolation requirements for equipment like laser interferometers and coordinate measuring machines.

The ZDT-B Series pendulum-type air-bearing isolators optimize horizontal natural frequency (1.0-1.5Hz) based on pendulum principles, achieving 5Hz isolation efficiencies of 86-92% vertically and 88-94% horizontally. These are ideal for highly vibration-sensitive applications like microscopes and nano-machining.
