With the rapid development of society, science, technology, and the economy, space utilization has become increasingly important. To save space, mechanical and electrical equipment is often installed on the rooftops and floor slabs of main buildings or podium structures.
Typical rooftop and floor-mounted equipment includes:
During operation, such equipment generates mechanical vibration and noise, which can seriously affect living and working environments.
Impacts of Vibration
1. Impact on projects and equipment
Vibration reduces overall project quality.
Continuous vibration shortens equipment service life and may cause premature damage.
Excessive vibration levels may lead to complaints if allowable limits are exceeded.
2. Impact on human health
3. Impact on buildings
Long-term vibration can damage building structures, commonly resulting in cracks in foundations and walls, surface peeling, displacement, deformation, and foundation settlement.
In severe cases, structural safety may be compromised.
Requirements for Vibration Isolation
Rooftop equipment typically generates low-frequency vibration, often below 10 Hz. Conventional rubber and spring isolators have relatively high natural frequencies—approximately 12–15 Hz for rubber isolators and 7–8 Hz for standard spring isolators—resulting in limited isolation performance at low frequencies.
Therefore, effective vibration isolation requires vibration isolators with sufficiently low natural frequencies. To meet this demand, Anlijing has developed a new generation of low-frequency vibration isolators, along with corresponding selection and installation solutions to ensure optimal vibration control performance.
Anlijing Vibration Reduction Technology Co., Ltd. specializes in the research, development, and manufacturing of vibration isolation products for a wide range of electromechanical equipment. The company offers five major product categories, including spring isolators, rubber isolators, air-film vibration isolators, air-cushion vibration isolators, and wire rope isolators, with thousands of models and specifications to meet diverse application requirements across the electromechanical industry.
In addition to standard products, Anlijing provides comprehensive vibration control services such as on-site vibration measurement, isolation system design, and customized product development, delivering reliable and effective vibration reduction solutions tailored to specific operating conditions.
