Vibration Isolation Springs: Core Principles
* Elastic deformation: When subjected to external forces (such as the weight of equipment or vibration impact forces), the spring undergoes elastic deformation.
* Energy conversion and isolation: When the external force changes or is removed, the spring releases the stored energy and attempts to return to its original state.
* Absorption of vibration energy: Some of the vibration energy is converted into potential energy and thermal energy within the spring (through molecular friction within the material or additional damping).
* Alteration of vibration frequency: The spring-mass system (composed of the isolated equipment and its base, which constitutes the mass) has its own natural frequency.
* Isolation of vibration transmission: When the external excitation frequency is much higher than the system's natural frequency (typically requiring the excitation frequency to be > 1.414 times the natural frequency), the spring can effectively prevent most of the vibration energy from being transferred to the protected structure (foundation, building, other equipment) or entering the protected precision equipment.
