Chinese engineers have completed the CHIEF1900, a hypergravity centrifuge capable of generating forces 100 times stronger than Earth's gravity. Constructed by Shanghai Electric Nuclear Power Group and delivered to Zhejiang University, the machine will simulate catastrophic events like earthquakes and dam failures in a controlled lab setting. With a capacity of 1,900 g-tonne, it surpasses previous centrifuges, including the CHIEF1300 and a US Army Corps of Engineers' device. The facility, built underground to minimize vibrations, is part of China's initiative to boost research and international collaboration.
