·The spring isolation system consists of springs, damping, and mass, with springs (generally referred to as) and damping being key components of the elastic foundation
·Steel spring isolators have low system frequency, high elasticity, large bearing capacity, accurate parameters, and long service life, making them ideal vibration reduction and isolation products
·The natural frequency of an elastic foundation is between 2 and 5Hz, and the frequency ratio should be greater than 3. It has high isolation efficiency and can generally attenuate by more than 80%
·The elastic foundation is basically maintenance free, once installed, has no operating costs, and is sturdy and durable
·Elastic foundations are also suitable for passive vibration isolation applications, such as precision equipment such as machining centers, roller grinders, and coordinate measuring machines
Focusing on the field of new infrastructure, making construction safer, more convenient, and more economical, becoming a pioneer and leader in technological innovation in the construction field.
·Basic Parameter Table for Isolator Selection
frequency ratio | Vertical natural frequency | System damping ratio | transfer coefficient | vibration isolation effect |
≥3 | 2~5Hz | 0.05~0.15 | 0.33~0.01 | 66.7%~99% |
