1、 The starting point of the principle of vibration isolation platform: analysis of vibration transmission path

The design of vibration isolation platform needs to start from three aspects: vibration source, transmission path, and controlled object. External vibrations (such as building shaking and equipment operation) are transmitted to the platform through the ground or air, and then transmitted to precision equipment through the platform structure. The core of vibration isolation is to reduce the natural frequency of the system through elastic support, so that the vibration energy is greatly attenuated during the transmission process.

LeadTop's LVH-T15 platform uses a four stage air spring to reduce the system's natural frequency to below 0.5Hz, effectively isolating low-frequency vibrations. At the same time, it compensates for high-frequency residual vibrations through electromagnetic actuators, forming a "passive+active" double-layer protection.

2、 Multi degree of freedom control: response to complex environments based on the principle of vibration isolation platform

Actual vibration often includes multiple directional components such as up and down, left and right, front and back, and rotation, and traditional single degree of freedom isolation is difficult to meet the requirements. LeadTop's LVH-T15 platform utilizes six degrees of freedom control technology to simultaneously suppress vibrations in three translation and three rotation directions, making it particularly suitable for devices such as electron microscopes that are sensitive to angular deviations.

its 35dB@5Hz The low-frequency attenuation capability can eliminate the interference of building sway on imaging quality, and improve the resolution of cryo electron microscopy by more than 30%.

3、 The Contradictory Balance between Lightweight Structure and High Stiffness: The Principle of Vibration Isolation Platform

The vibration isolation platform needs to achieve a balance between lightweight and high stiffness: lightweight can reduce inertia and improve response speed; High stiffness can reduce its own deformation and avoid introducing new vibration sources.

LeadTop's MOT-F platform adopts a honeycomb core design, which reduces the weight by 40% compared to solid structures. At the same time, the stiffness is doubled through the trapezoidal thin steel plate bonding process.

Its fully sealed hole structure and equidistant array flatness design ensure that the deformation under long-term use is only 0.05-0.1mm/m ², meeting the ultimate stability requirements for semiconductor testing.

Summary: Technological Evolution of Vibration Isolation Platform Principle: From Single Function to System Solution

With the development of precision instruments towards higher resolution and speed, vibration isolation platforms have evolved from simple vibration isolation tools to system level solutions covering vibration analysis, parameter optimization, and online compensation.

LeadTop covers the full range of requirements from heavy-duty equipment to lightweight optical instruments through its LVH-T15 and MOT-F product lines, providing a full chain support of "principle technology product" for scientific research and industrial fields.
