新华鲜报｜世界最大！我国超重力实验装置启动核心设备

Core Insights - The world's largest supergravity experimental facility has been launched in Hangzhou, China, featuring a centrifuge capable of generating gravitational forces up to 1500 times that of Earth's gravity [1][2]. Group 1: Facility Overview - The supergravity centrifuge simulation and experimental facility is led by Zhejiang University and includes three main centrifuges and 18 onboard devices across six experimental chambers [1]. - The first centrifuge, "CHIEF1300," has a capacity of 1300 g·t, making it the largest centrifuge globally, with two additional centrifuges, "CHIEF1500" and "CHIEF1900," under construction [1]. Group 2: Purpose and Applications - The facility aims to recreate significant disasters, geological evolution, and extreme environments in a controlled setting, allowing researchers to conduct experiments that compress time and space [2]. - For instance, a 100-meter real object can be scaled down to 1 meter, and a 100-year pollution migration process can be simulated in just 3.65 days [2]. Group 3: Technical Implementation - The "CHIEF1300" operates in a circular underground chamber of approximately 230 square meters, utilizing a 6.4-meter radius arm to generate centrifugal force, achieving supergravity levels between 10 to 300 times that of normal gravity [3]. - Advanced technologies such as deep pits, low-pressure chambers, and liquid cooling walls have been implemented to ensure stable and high-quality operation of the facility [3]. Group 4: Research and Development Impact - The facility integrates supergravity fields with extreme environments, covering various fields such as deep-sea resource development, disaster prevention, waste disposal, and new material fabrication [4]. - Preliminary experiments have yielded significant findings, including safety assessments for methane hydrate extraction at 2000 meters depth and earthquake impact simulations for hydropower dam designs [4]. - The facility aims to establish an open and collaborative international research platform, fostering partnerships with leading global research teams [4].
