Different Types of Vibration Isolators: A Selection Guide Based on the Principle of Operation

Vibration isolators are key components for reducing vibration interference and protecting equipment stability. Their type should be selected based on the application scenario. Vibration isolators based on different principles have different performance focuses. Below, we analyze the mainstream types based on their principles of operation to provide a reference for equipment protection.

Passive Vibration Isolators: The Choice for Basic Protection

Passive vibration isolators rely on elastic materials such as springs and rubber to absorb vibration energy. LeadTop’s passive vibration isolators, the POT-P series solid rubber isolators, use solid rubber damping with a damping ratio of 0.05 to 0.2, providing excellent basic stability for instruments.

Active Vibration Isolators: A Tool for Precise Vibration Control

Active vibration isolators use sensors to monitor vibration, and a controller drives an actuator to generate a counterforce to offset interference. LeadTop’s LHV series active vibration isolation modules, combined with six-degree-of-freedom precision active control, achieve low-frequency vibrations of 0.5-20Hz. They are suitable for high-precision applications such as acoustic laboratories, medical imaging, and quantum research.

Composite Vibration Isolators: A Comprehensive Solution

Compound vibration isolators combine passive and active principles, passively attenuating high frequencies and actively compensating low frequencies. LeadTop’s ZH series comprehensive application workbenches feature a modular design that allows customization of tabletop thickness and hole spacing, meeting diverse needs from teaching to research.
