Foreign media: Chinese scientists said that the riding experience of Musk's "Hyperloop" might be extremely uncomfortable, and have proposed an improvement plan. Chinese scientists pointed out that Elon Musk's proposed "Hyperloop" has a critical defect: even in a nearly vacuum pipeline, slight unevenness in the track or deformation of the bridge will cause severe bumps, making the riding experience extremely uncomfortable. This study was published on May 16 in China Railway Science and Engineering Journal. The author is an engineer team led by Zhao Ming (name translated) from the electromagnetic propulsion team of China Aerospace Science and Industry Corporation. They conducted experiments on the world's first full-scale test line in central China and found through supercomputer simulation and scaled prototype testing that track unevenness and electromagnetic resonance would cause intense low-frequency vibration. At a cruising speed of 1,000 kilometers per hour, the strongest vibration occurs at 400 kilometers per hour, which, according to the "Sperling Index", an international comfort standard in the 1940s, is "extremely uncomfortable". However, the team has found a way to reduce turbulence intensity by nearly half, significantly improving the riding experience.
