China has unveiled a new hypergravity research machine capable of producing forces nearly 1,900 times stronger than Earth’s gravity. The device, named CHIEF1900, was developed at Zhejiang University in eastern China.
The centrifuge is part of the Centrifugal Hypergravity and Interdisciplinary Experiment Facility. It allows researchers to study how extreme gravitational forces affect materials, plants, cells, and other structures. Scientists can now simulate catastrophic events, such as earthquakes or dam failures, in controlled laboratory settings.
CHIEF1900 can also test the structural stability of large-scale infrastructure. For instance, researchers can spin a ten-foot model of a 1,000-foot-tall dam at 100 Gs, or 100 times Earth’s gravity, to observe how it behaves under extreme stress. The machine can support studies on high-speed rail track resonance and the long-term movement of pollutants through soil.
The new machine surpasses its predecessor, CHIEF1300, which became the world’s most powerful centrifuge just four months ago. CHIEF1900 can generate 1,900 g-tonnes of force, while a typical washing machine produces only about two g-tonnes.
Officials at Zhejiang University said the machine opens new opportunities in material science, civil engineering, and environmental research. By recreating extreme forces, scientists can better understand how structures and natural systems respond to stress. This could help improve safety in real-world infrastructure projects.
Experts highlight that China is now at the forefront of hypergravity research. CHIEF1900 allows experiments that were previously impossible, giving researchers a powerful tool for scientific discovery.
