The initial test of the super large air spring vibration isolation foundation platform was successful.

The super-large air spring vibration isolation foundation platform, independently developed by Professor Tan Jiubin from the Institute of Ultra-precision Optoelectronic Instrument Engineering, has achieved significant success. This breakthrough represents a major step forward in the field of ultra-precision testing and engineering applications. As a core technology for constructing large-scale ultra-precision test platforms, super-large air spring vibration isolation is one of the most challenging aspects in establishing advanced research laboratories and critical engineering systems. To address the challenges of heavy-duty and ultra-low-frequency vibration isolation, Professor Tan’s team conducted extensive research and developed several patented technologies, including multi-position air-floating balance precision monitoring, feedback control, and multi-level residual vibration suppression. These innovations are based on independent intellectual property rights and have significantly improved the performance of the system. After nearly a year of dedicated effort, the research team successfully completed the design and engineering implementation of three super-large air spring vibration isolation foundation platforms. The largest among them measures 11 meters in length, 3.7 meters in width, and 2.6 meters in height, with a total weight of approximately 180 tons. Preliminary tests showed that the vibration isolation frequency is better than 0.8Hz, which demonstrates that our university's development of this large-scale air spring isolation base has reached an international advanced level. This super-large air spring vibration isolation technology is essential for large-scale, high-precision test equipment, cutting-edge technical devices, and advanced manufacturing systems. It serves as a key indicator of a nation’s capability in high-end equipment manufacturing and testing. By independently developing the fundamental technology for super-large air spring vibration isolation, our institute not only saved millions in research funding but also secured a crucial foundation for future ultra-precision research and testing. This achievement marks a milestone in our school’s efforts to build world-class experimental facilities and support cutting-edge scientific and technological innovation.
